PVP is a joke in this game.
Almost all the skill shots ( think league of legends ) are ground level, and there is no targeting system.
This is not new information, you can see it from there videos.
So essentially you can mouse turn, and double jump all the time. Only landing for your random skill shots.
One person doing that can take out a group of 5. I couldn't believe it the first time I witnessed it.
My guess is this has to change for release. All classes would have to have skills where they can lock on, and ground a player for a long period of time.
Honestly it's just a travesity of a system right now. To me it seems like another game where PVP will be an afterthought, because it wasn't designed to work with they way designed pve.
