Adapt or quit, I suppose is a good summation of the leveling experience AA brings currently (and rescorlas post), I don't really see an inbetween.
I mean if PVP gave decent xp/coin/anything I'd definitely see there being an inbetween.
Currently though, PVP is just a means of limiting other players, "Legal Griefing" I suppose you could say. There's really no absolute reason to do it other than to inconvenience other players.
If I could take some of their on hand cash, or gain 1% xp for a kill, or something... my tune would change on the subject.
