Death Knight: Light Master (we NEED deathknights but using holy light!! How cool and different would that be??)
Demon Hunter: Skymaster (games first flying DPS, ranged eye blasts and melee swoops)
Druid: Drugs (name not final, uses psychoactive chemicals on themselves and opponentd, ranged DPS, kinda like an alchemist that uses their own stuff too)
Hunter: Distractor (ranged tank)
Mage: Chronomancer (Healing and dps, cannot do any damage or healing but can reverse any damage or healing that is done in different ways)
Monk: Ascetic (healer, kind of like a priest but they have even LESS fun and self-flaggulate)
Paladin: Dark Knight (so much unexplored design space for a paladin using unholy magic!!!)
Priest: Voidcaller (Tank, literally just a tentacle monster)
Rogue: Pirate (but really this time, ranged/melee hybrid)
Shaman: Wolf (off tank and DPS, spirit Wolf ect removed from other specs)
Warlock: Lich (literally immortal tank, goes back into phylactry for a bit when HP is zero)
Warrior: Medic (Bandage and first aid healer, profession is removed so now there's design space)
