I wouldn't expect to get end game gear tokens from running through a level 20 flashpoint, so why do I get pvp tokens from killing lvl 20 players?
Proposal!
1-49 bracket gives warzone coms
50 normal gives centurion coms
50 Heroic gives champion coms
Let people queue for the tier they want, it wont stop the odd griefer, but if there are no rewards it will stop high level guilds just farming lowbie kills. Also it will do away with the largely hated RNG bag of disappointment.
The first response is almost certainly going to be, "its fine how it is, L2P n00b." and my response is, "I thought this game was aimed at the casual market? Barring people from PVP because they don't have 60 hours a week to play is not catering to the casual player." (You didn't get that full centurion set in a Sunday afternoon, don't say it, you fooling no one )
