And dwarves were able to drop the tank debuff of Zul without needing paladin Blessing of Protection to my knowledge, which removed a large chunk of focused healing from the tanks that healers could allocate to a different individuals, or use more mana to DPS instead.
Same with the tank bleed on Conclave of the Chosen in BoD, but I wouldn’t count that since both factions had access to dwarves there (just like Alliance had access to trolls, considerably more trolls than what the Horde had mind you if the stats from realm pop could be delieved from that time.) Both Worgen and Night Elves turned into trolls from the Alliance side.
I always find it questionable when someone brings Jaina up. Alliance had access to the exact same racials as Horde did on her.
Stoneform broke the Stone Legion Generals fight, and mind you this is the only fight where Stoneform and the vial does not work. It works on every other bleed so Alliance still has their advantage (just like they always do when a bossfight has bleed of any form.)
As to the whole KJ fight it only affected priests, and priests only. Beside priests and shamans none of the other players in Method’s roster on the kill vid were goblins.
Demon Hunters also broke the fight there, since double jump just countered the knockback, every single one.
World first raid KJ had 1 goblin. still it is “important horde bias”. these guys just leaped and used a warlockportal. You exagerate so much.
They had two priests, and their shamans tend to go for goblin, so there were alteast three. Still, the point stands that priests were the ones that were struggling because they had a single orb phase that they couldn’t do anything with.
