First off, I love the snarky comebacks people throw in when someone points out an obvious imbalance in the force. This doesn't help anyone.
Secondly, we have better methods/resources to fairly pair players, like quests, achievements etc. I don't know why nobody has mentioned this..
GP is one way to measure someone's power, but specific quests and achievements seem to be better dialated to the actual method or strategy said player is obtaining individual GP. Many of which are rewarded/completed upon unlocking meta characters.
I think it would help eliminate the PvP shortcut player's (myself included) advantage that has been used to gain an edge over other, broader focused players.
Just my two cents..
