People ruin communities. I have been in groups in SWTOR who HAVE NOT SAID A WORD and also rolled on items they cant even use. So you say the social part is sitting in the fleet spamming "LF2M tank & heals D7" 100x in general chat social? yeah buddy, whatever you say.
By the way WoW's community never was ruined, it has always been the same (troll heaven). People on my realm STILL use chat to make dungeon groups, go figure.
