Warriors in Classic (and in Everquest, the game that WoW is based on) primarily hold aggro through their melee DPS. They have plate armor to survive attacks, unlike Rogues who have threat reducing abilities (Vanish, Feint) and Evasion to avoid attacks.
They are simply two sides of the same coin. Your definition of “hybrid” comes from playing the expansions, where classes are defined by their spec.
Not aimed at directly at you but when someone keeps pointing this out I assume there’s a reason for it and hopefully not one steeped in bias like Im sure it will be.
I’m speaking about the terms and the context of wow not everquest.
You know the game we’re playing and talking about?
World of Warcraft was not some laissez-faire fair approach to building your character to do Anything you want and yet you can still do anything you want. It wasn’t the Type of open build style RPG like other games at the time. You’re sort of more leaning into the dungeons and dragons style gameplay of games like Divinity sin or balder’s gate where you have respectively a lot more freedom in every aspect of what your character is capable of doing.
All 3 warrior specs require them to be in close combat and hitting their target with a melee weapon. Hitting your target up close with weapons is one role and one part of another.
The original 3 roles were actually tank, heal, and crowd control. Not damage. Your Blizzard post from 2006 that you linked a few posts above even says as much:
A Rogue is NOT a hybrid because they deal melee damage, that is their primary role. They cannot heal, tank, or crowd control (sap aside).
“Damage” is not a role in Classic WoW. All classes can do damage.
Hunters have okay tanking abilities + CC abilities + ranged abilities + melee abilities + a mix of physical and magical damage… aside from Druids, yes, Hunters are the most stereotypical hybrid in Classic WoW.
