They have putten time in pvp? As far as I know, they never have put any time in pvp at all, so don't worry all that nice good subscription money you pay every month is going right into the hands of a big warner brother exec and his car collection. As for the small percentage, perhaps so but it's still thousands upon thousands of very active players, usually with a lot of toons.
We don't need anything changed, we just ask for maybe some bigger area to pvp in, maybe some extra dimension, which if they did, it would help the game immensely not only by popularity but by diversity aswell. The fact Turbine does not care about pvp is simply cause they aren't caring about the game as a whole but more about, ah yes, your subscription money, store items to milk money from. So this is pretty much linked to the whole game experience.
