#Nochanges has been supported with varying degrees of “intensity” by the community, but only a minority advocated for the most literal interpretation of it.
Many people like to claim that “nochanges has failed” for such stuff as Black Lotus spawn change, 30-instance limit, and other “fixes” that, for good or ill, happened to Classic. But most #nochangers have been advocating for no changes on a more fundamental level.
Like, personally I don’t give a damn in TBC if, say, Blizzard tweaked the rollout of PvE and PvP content slightly, or changed spawntimes or introduced layers. The point of #nochanges is to not get stuff like LFR, class changes or other drastic alterations of the original gameplay. Everything else you hear from the #prochange field is generally a thoroughly insincere exaggeration of the concept to make their outrageous proposals look more reasonable.
Such as, say, giving SoB to Alliance Paladins.
