There's the problem with the loot that has to be spread between 40 people where healer cloth gear will automatically visit paladins, leather dps to rogues, tank equipment to warriors and etc.. Some specs are reliable for PVP but you still must be accepted in raids so as to farm equipment because boss items are good for PVP too, so people will not throw themselves into the hell pit just to experience another course.
Given up on WoW Classic already. Ion's conclusions have nerfed raid content to be simpler than LFR along with the huge material streamers need WoW Classic shifted for their biases. Seriously f#%# it. I'll play Nostalrius 2 and observe Blizzard go bankrupt catering to people who roll a course like warrior, expire to par 10 murlocs and
cry in their paladin not being all powerful with a victim complex. Have fun with a transformed, broken WoW Classic according to individuals who don't realize that you can't have 40 man raids without a lot of healers, and not realizing that ALL CLASSES RESPEC TO RAID including mages, rogues and warriors. The mage frost PVE spec in early tiers does not even have shatter. It's horrible, yet you think they magicaly have the identical spec for PVE, goldfarming and PVP.

Meanwhile in 1.12
