Just give "For the Horde!" and "For the Alliance!" skills to every player that start at 5 min CD at level 10 and go down to 90 seconds (I'd prefer 60 tbh) by max level, and leave the racials as the toher aspects, ensuring everyone gets the "PvP trinket" effect.
Then make PvP trinkets more interesting by getting rid of the mandatory CC break part and putting something more fun on.
