Id take everything that happened in OG TBC and Classic with a huge grain. The playerbase was complete trash. Your average raider in a middle of the road guild right now would give those world first people a run for their money. Had they known what we know now they 100% wouldve been using it. They just didnt have the information and thats all that stopped them. Not some false sense of self righteous purity.
Im actually really happy that blizzard discussed it and decided to do nothing about it. Let the players choose. The content is doable without them if players decided not to use them. if anything this just brings melee in line a bit more and threatens those poor poor ranged apes stack meta (it really doesnt but its comical to watch). I am happy they ignored the people who are incapable of making adult choices for themselves and want sweeping changes to others enjoyment to fit their needs. Ignore them like you ignored the people who cried about worldbuffs. Both thought they did but are learning they didnt.
