WoW Classic Hardcore mode is a challenging way to play the game, where you have to start over from level 1 if you die. It requires careful planning, strategy, and skill to survive and thrive in this mode. If you want to be ready for Hardcore mode, you can buy some Classic hardcore gold to get a head start!
There are many factors to consider when choosing a class for hardcore modes, such as survivability, solo ability, leveling speed, gear dependency, utility, and fun. Some classes are more suited for hardcore mode than others, and some may have different strengths and weaknesses depending on the race, faction, spec, and playstyle.
In my opinion, the best classes for hardcore mode are Hunter, Shaman, Druid, and Rogue. They are all very versatile, self-sufficient, and fast at leveling. They also have good escape mechanisms, healing abilities, and crowd-control options. The worst classes for hardcore mode are Warrior and Paladin. They are very slow, gear-dependent, and vulnerable to certain enemies. They also have limited mobility, damage output, and mana efficiency.
Of course, these rankings are not absolute or definitive. They may vary depending on your personal preference, skill level, and luck. You may find that some classes are more enjoyable or challenging than others, and also discover some hidden gems or pitfalls.
Hunter
Hunter is a fast and versatile ranged class that can deal damage, control, or support with its bow, gun, or crossbow and its pet. You can choose it from three specializations: Beast Mastery, Marksmanship, or Survival, each with its own strengths and weaknesses.
Beast Mastery is the best specialization for leveling in hardcore mode. Beast Mastery Hunters are a great choice for players attempting the hardcore leveling challenge in WoW Classic. With their high survivability, mobility, and solo ability, they are capable of handling many different challenges solo. They can also use their tracking abilities, stealth detection, and feign death to avoid unnecessary combat or escape from danger. They deal damage primarily through their pets, which scale entirely independent of gear and have a large toolkit of abilities. They also have various shots and traps to add damage and utility to their attacks. In terms of survivability, they can heal themselves and their 
pets with food and 
bandages, reducing the risk of death. Beast Mastery Hunters are highly effective in both solo and group play, making them a strong choice for players looking to take on the hardcore leveling challenge.
Shaman
Shaman is a unique and versatile class that can play as a damage dealer, a healer, or a hybrid of both.
There are three main specializations for Shaman: Elemental, Enhancement, and Restoration. Each spec has its own strengths and weaknesses and may suit different playstyles and preferences.
Elemental: This spec focuses on casting powerful spells that deal fire, frost, or nature damage. Elemental Shamans have high burst damage and good AoE capabilities and can benefit from clear-casting procs that reduce mana costs. However, they also have low survivability, high mana consumption and can be easily interrupted or silenced by enemies.
Enhancement: This spec focuses on enhancing your melee attacks with weapon buffs, totems, and shocks. Enhancement Shamans have consistent damage, good utility, and can use various weapons and shields. However, they also have low mobility and high gear dependency and can struggle against multiple enemies or ranged attackers.
Restoration: This spec focuses on healing yourself and your allies with efficient and powerful spells. Restoration Shamans have excellent mana efficiency, strong single-target, and group healing, and can use totems to buff or protect their party. However, they also have low damage output, limited offensive options, and can be vulnerable to dispels or crowd control.
Druid
Druid is a versatile and fun class that can play as a damage dealer, a healer, or a hybrid of both. There are three specializations for Druid: Feral, Balance, or Restoration, each with its own strengths and weaknesses and may suit different playstyles and preferences.
Feral Druids are a great choice for players attempting the hardcore leveling challenge in World of Warcraft Classic. With their high survivability, mobility, and solo ability, they are capable of handling many different challenges solo. They can also use their cat from stealth to avoid unnecessary combat or ambush enemies. They deal damage primarily through melee attacks, adding additional damage and utility with their skills and buffs. They also have defensive abilities, such as nature's grasp and barkskin, which can be used to protect themselves and others from harm. In terms of survivability, they can heal themselves with food or potions, reducing the risk of death. Feral Druids are highly effective in both solo and group play, making them a strong choice for players looking to take on the hardcore leveling challenge.
Rogue
Rogue is a fun and exciting class that can deal damage, control, or support with its various skills and stealth. There are three specializations for Rogue: Combat, Assassination, or Subtlety.
Combat Rogues are a great choice for players attempting the hardcore leveling challenge in Classic WoW. With their high survivability, massive burst damage, and variety of supportive abilities, they are capable of handling many different challenges solo. Combat rogues deal damage primarily through melee attacks, adding additional damage and utility with their weapon buffs and cooldowns. They also have defensive abilities, such as Evasion and Vanish, which can be used to protect themselves and others from harm. In terms of survivability, they can heal themselves with bandages or potions, reducing the risk of death. Combat rogues are highly effective in both solo and group play, making them a strong choice for players looking to take on the hardcore leveling challenge.
Priest
Priest is a versatile and durable caster class that can heal, damage, or support with its light and shadow spells. A priest can choose from three specializations: Discipline, Holy, or Shadow, each with its own advantages and disadvantages.
Priests bring together light and shadow, mastering the ability to both give and take life. A Discipline Priest in many ways, is defined by its chosen subspecies and can make excellent use of that duality to push the limits of the class.
Warlock
Warlock is a powerful and versatile caster class that can deal damage, control, or support with its dark and demonic spells. A Warlock can choose from three specializations: Demonology, Affliction, or Destruction.
Demonology Warlocks are masters of control and resource management and one of the most durable and versatile classes in WoW Classic. They have access to powerful demons, strong crowd control, and a variety of defensive abilities. They can also deal decent damage with their DoTs and nukes, although they are not as fast or efficient as other Warlock specializations.
Mage
Mage is a powerful and versatile caster class that can deal damage, control, or support with its arcane, fire, or frost spells. A Mage can choose from three specializations: Frost, Fire, or Arcane.
It is highly recommended that you level your Mage in the Frost spec for hardcore, as the name of the game is survivability, and this spec is unmatched in that regard. For players wanting a change of pace from Frost, Fire is also a very strong single-target spec losing out on a bit of survivability for bigger damage, and it is a lot of fun to level in. Arcane is fine and a lot of fun too, but not recommended.
Warrior
Warrior is the most difficult class to level in the Hardcore challenge in WoW Classic by a large margin. Warriors lack the damage, crowd control, AoE, self-sustainability, buffs, and escape tools that other classes possess, especially at low levels.
However, despite these challenges, Warrior is a popular class in Hardcore mode. Warrior is an incredibly fun class to play: gear and weapon upgrades are extremely impactful. They're the best dungeon tanks, the best and most in-demand class at level 60, and there's something fun about the added challenge of playing the hardest class in the game.
Paladin
Paladin is a holy and righteous Warrior class that can heal, damage, or support with its light and holy spells. A paladin can choose from three specializations: Retribution, Holy, or Protection.
Retribution Paladins are a great choice for players attempting the hardcore leveling challenge in Classic WoW. With their high survivability, massive burst damage, and variety of supportive abilities, they are capable of handling many different challenges solo.
Ultimately, the best class for hardcore mode is the one that you have the most fun with. Hardcore mode is not meant to be easy or optimal. It is meant to be an adventure that tests your limits and rewards your efforts. So choose a class that suits your playstyle and personality. After that, if you are tired of leveling up, the fast way is to buy WoW Classic Era hardcore boost service from a third party, like MMOGAH.
