BG leveling healer group - suggestions??

With so many groups running I'm getting tired of seeing the same quests and instances repeatedly. I'd like something different to change things up for a while.

After reading about Apps leveling priests in bgs, I want to do the same thing. I love healing in BATTLEGROUNDS. My problem is that I dont have five healers at 60. I only have four (accounts with) unused healers. I'd like some suggestions as to what would be the best composition to run. My favorite class is priest so i'd prefer it to be priestx4 + something.

Here is what I have available sitting at level 60:

ACCOUNT1: priest, shaman, paladin, druid

ACCOUNT2: priest, paladin, hunter, warrior

ACCOUNT3: warlock, mage, warrior, hunter

ACCOUNT4: priest, hunter, mage, warlock

ACCOUNT5: priest, paladin

I have an idea but i don't want to influence what others come up with.
What is your idea and the rationale behind it?
Thanks!:D

I've never used a warrior for PVP before, but I can see that being fun with 4 priests.

2nd vote would be warlock.

I know when I leveled Warrior + Shammies to 60, it was fun and useful to control the Warrior from the PoV as the shammies, kind of like a really far zoomed out camera where you see the tank run around with a full view of the battlefield and move with Interact With Target.

How that would work out in PVP, I don't know... I'm still to nervous about all the comments when I eventually box in a BG so I am saving that for my 2nd 85 team.

Changing the viewpoint like that was definitely was a moment where 5-boxing clicked for me as to how flexible things really are when you adjust perspective.

Personally I like all the same range.
Whether they're ranged classes, ranged classes with a healer, etc.
Or melee toons, or melee with a melee range healer.

For PvE, I don't mind mixing Melee and Ranged.
But it's a pain in pvp.
