Pvp was never made to level, never has been, never will be. It's about showing off your skill and aproach to the game, and any professional (term used lightly) doesn't give a shit about leveling as long as they're having fun. I'd agree to having rare drops or more events for pvp, but not increased rates. Base is much the same, I'd suggest this: raise base health, and increase the amount of gold it drops, if the game detects someone who takes all the gold, they only get a partial amount.
