PvP in this game already scales everybody to the same stat allocation regardless of their level. Presumably, open world PvP would adhere to the same approach. A level thirty WAR is equal to a level eighty WAR.

It'd be as simple as toggling it on and switching from PvE to PvP hotbars - something that already happens in PvP maps and the Wolve's Den. If it's entirely opt in, I really don't see the problem with it.

PvP is something that a decent chunk of players enjoy and pursue. I like it quite a bit myself and wish it received more focus, not less.
