The state of casual PvP (which most people play) was bad enough as it was because of healer skill/gear/AMOUNT imbalance, if you're matched in a bg with less healers than the enemy team you need a miracle to have even a glimpse of hope.
Balancing all PvP around the damage dished out in competitive play hurts most of the community. Healers getting out of hand in 2s again I guess.
