Since Lich King I've played almost all my arenas with the same spriest. We've had a couple healers over that time. Our current healer is a mistweaver reroll without much historical pvp experience, but she's well proven absolutely top notch in pve. The skillsets aren't the exact same, but that should be ok.
This has proven a pretty brutal expac to bring her into arenas, as she's basically sitting in CCs a preposterous amount of time.
What was recently proposed was, the priest goes disc, and we two heal it. In past seasons, double healer / rogue has been pretty poor. Even in seasons with rogues very strong, it's simply not normally a class with the required uptime and sustained damage to wail away a mana pool, and the burst is normally counterable with CC. But this season, we do see some high rated double healer / rogue comps- the healers in question I believe are disc priest and resto shaman. A monk is obviously not ideal, but that's Blizzard's problem IMO.
So here's my questions:
1)- Should I even try this? Keep in mind, our current comp is sub / spriest / mist, so the question is mostly "is this better".
2)- If we do, how do we score kills? Do I save blades for an opponent who has no defensive cools left and cloak to prevent peels, or do I use blades to GET the cools, and make the kill with just dance?
3)- Is anyone here running double healer 3s and has advice? In all my years of playing, the only time I did double healer 3s was on my rdruid alt in like LK, and that was with a warrior DPS.
