I'm not here to criticize the changes to ToTC or changes to Ulduar relevance, I honestly have less of a problem with that than the level boost and mounts/toys. I think those have absolutely no place in classic and I personally think those should never have been a thing. However, if there wasn't a near-monolithic and giant group of players that started the #nochanges trend I highly doubt blizz would've kept it only at the mount and levelboost but would've added token sooner or later as well as more mounts, pets, toys etc. It would've been the same shitshow retail is now by the end of TBC. Classic only exists because of community and the monitory power it represents, and blizz knows these customers are far more strict than retail players, they will hold blizzard accountable and will vote with their wallets if blizz really messes up. It's mostly a group of people that for the most part have already abandoned blizz once for their actions and will do so again if they think blizz's products aren't worth it. Blizzard needs them to try and salvage any semblance of their old rep too.
