A company that does player staff feedback well...
Is Anet. I have, in all my time playing gw2 (couple hundred hours), heard anyone say anything like:
fuck anet
anet sucks
anet never responds to the payers
anet completely screwed up on x, y, or z
Gw2 has patches every two weeks... some of which change pvp balance a LOT. But... somehow... they are able to deliver on what people want...
Riot, being on the boards, like, ever is not hard. I have responded to more threads on the front page than any rioter... significantly.
