If every complaint is considered valid, are those that are fine with the changes not considered valid and valuable as feedback as well?
The moment someone disagrees that the changes are bad, everyone will jump on said person for being wrong. Looking back at the thread, you'd see that PirateIzzy was the one who started the spiral by insulting everyone who sided with the changes, and then the whole thing devolved into a flame pit a page later. So fine, lets ban everyone in that topic that insulted others; Gasp! that'll mostly be those who voiced their opinion as against the changes.
Guess what kind of picture folks will think the mods are painting then. Actually, it's so blatently obvious that folks will be calling out mods for silencing 'criticism', ignoring that those posts contained insults.
Data for KMS, not for GMS. If you're going to assume that it'll be a C&P job, it's safe to assume that the response given by Nexon Korea as reasoning should be valid until GMS provides a response themselves (if they ever do). Dismissing it as a misconstruction is pointless when you're building your argument on the basis that GMS's patch will mainly follow KMS (with the small additions not found in their version like familiars, etc.).
