This is nothing new. If you played any other MMORPG, which most probably hails from Korea, the devs will favor feedback and inputs from their own people, the Korean playerbase, even if EN is the majority and KR the minority in players.
Square Enix is no different, they will only listen to JP playerbase and "pretend" to listen to EN but will do nothing actually. Companies like Blizzard, ZeniMax (ESO) and ArenaNET (GW2) are Western companies which means they'll listen to feedback from EN community most.
