Nah.. Pvp is not really needed in my opinion.. And if they do put it in then make it so the playes has to agree with it.
We don't need some noob lvl 50 beating up lvl 25's cause hes an ass player.
Every player deserves to play for fun not just the high lvls.
A lot of people would quit playing if they get butchered by high lvls all the time.
