I'm not saying it's going to be great, but it does have open pvp. I'm pretty disappointed they never added a pvp penalty for dying, but at least it is relatively interesting, if you can man up and not feel like a weaboo 12 year old girl to play.
We now have a small group testing the Wakfu beta. The game has a player economy and open pvp so there is high potential for it not to suck. So far most of us playing it are enjoying it thoroughly.
