Hm. I think you miss the point of fun in the game as a core-factor of what is wrong. I don't play pvp in gw2 because it's flat. It's boring. It's not fun. Fun should be the first incentive in any game/mode to play it. Change rewards won't make it any more fun to play.
What else can I say?
I still play gw1 random arena sometimes, just for fun. I don't care about reward.
It's about skill, builds and FUN.
