Sounds to me more like a battle high and soaring problem, and that those should be removed. Or alternately made even stronger so the matches can end more quickly. Most people are just there for the exp, series exp, or smashing their face against the wall for as long as it takes to eke out enough wins for the mount achievements. Completely removing all rewards except some end of season titles would work too, since then there would be almost nobody playing except those who actually enjoy pvp.
