SUGGESTIONS!
No. Anet doesn’t do things that make sense, such as putting more skills in the game to avoid player boredom.
The point of PvP is that everyone is on an even playing field. That way the outcome is determined by your SKILL not your gear. You can’t give advantages in PvP, all you end up with is the strong people staying strong and the weak or new people not being able to advance at all. Upgrading in PvP would kill PvP and prevent it from being anything remotely close to an e-sport…. WoW is not known for it’s PvP at all, in fact I’m pretty sure most competitive PvPers think WoW’s PvP is dreadful, so I don’t even know what you’re on about -_-
