a) No-one plays extinction, so there's no PVP there.
b) There's no oceanic extinction as far as I'm aware.
c) Unofficial servers are more or less extinction but they do it better, and they are more varied (This is what I primarily do now).
d) The 1 month wipe cycle is too short. I'm not suggesting that the official servers should be wiped monthly, nothing of a sort. But I do think that 6-12 months is more than enough time to enjoy the early and mid-game, get to max level, claim the server and say mission accomplished.
e) Me going and playing extinction doesn't solve the problem that Wildcard just endorsed cheaters and gave us a meaningless platitude of "We'll really ban them next time, we promise" while allowing them to maintain their server dominance where their sole objective is tear harvesting. Not fun competitive PVP.
f) If I was playing extinction and we were 2 weeks through the wipe cycle and tribes were duping/cheating I'd still expect them to get banned and/or the server to be wiped.
Does that about answer it for you?
