keeping heavy multipliers has the downside of... well they multiply
its hard to balance for example cross class slots+gems like rings for warriors+bears at the same time with those multipliers. the 12sta gem for example was simply too overpowered with the old hp multiplications.
while i dont like that everyone will go for specific tokens now either, its not like crafted blue gear from skill lvl 350 should be the endgame tanking gear for illiadan. that defeats the purpose of loot dropping in raid instances somewhat.
making class specific drops working in the benefit of their class seems obvious. just because itemization sucked for feral druids (pvp parts were some of the best raiding tanking+dps gear choices in the game) and ppl got used to get their easy to get items buffed with multipliers till they can use em, doesnt mean the changes arent right and good.
going into kara, gruul, maggy in clefthoof=good, leaving in t4=working as intended, needing t4 for SC+TK=working as intended.
the only thing missing is expensive epic crafted gear as an alternative to gruul/maggy/kara drops like tailors or blacksmith have.
