Once upon a time there was someone at Blizzard saying that the game should be about bringing the player and not the class and once again what you are describing here is that u think people should bring the class for the situation and not the player
People who have been subbed to WoW for a long time know that this is not a good change. We dont need to wait for Alpha or Beta or anything in order to determain it
It takes less than 5 seconds to know that this will affect this game in a major negative way. Thats why this becomes a hot topic instantly
Its been 15 years, you need to start take into consideration elements of the game that makes people feel that they are having fun.
Its completely wrong to nerf the entire game because the top players stacked certain specs in MDI and you dont want that to happen
The majority of player wouldnt even be able to pull something like that of anyway
This is where the design philosophy goes in the complete other direction compared to what the player enjoys
Players want to choose their class they like and BE VIABLE. Not be Situational
In Legion nobody ever talked about this because the majority of the classes had viable AoE in terms of damage and burstyness.
M+ was a lot more fun in Legion than it was in BFA because the developers at that time did not try to make anything they can to stop the players from doing massive pulls if they wanted
But when we had Reaping as a seasonal affix in BFA all of a sudden for 1 season in m+ was actualy more fun
People loved Reaping Affix in BFA like nothing I have ever seen in this game. If u want Shadowlands to succed Its incredibly vital you take feedback from that and try to enhance it instead of trying to counter it
Experiences like Reaping is what makes people hooked to this game
Classes and M+ was working towards the end of Legion, BFA created problem by trying to remake certain things that didnt have to be remade
Shadowlands are just trying to fix the problems BFA has which in reality was never even any problems in Legion
