Honestly, as much as no one wants to hear it, give it a little time, and SE will address this issue with healers. Team imbalances or tactics to fuel a bad meta are what they don't want (lest people begin avoiding the mode for that very reason). It's what got Sleep nerfed and Freelancer forced on premades. SE claims to read and take in feedback here, and the number 1 thing being said repeatedly is "Healers are too OP/Having multiple healers ruins balance/etc." I still say they ought to look to Soaring first so as not to rock the boat too much, but if that proves not enough, then bigger measures can be taken.

For now though, have patience, and keep the feedback coming. I'm asking a lot in saying that, and I know I'm notoriously impatient with SE's handling of PvP related issues. But something WILL happen. Because they can't afford not to do anything about it.
