Next team class make up?

My quad-shaman team is a lot of fun in the BGs when I group up with a healer or two (650 to 800 resil and 18 to 19.5k HP) but areanas of course are another story -- I dual-box two of the shamans for PVE (both dual specced and epic flyers with 4 out of 5 T7.5) -- usually I go double resto and stagger my heals with a /castsequence ,chain heal macro -- but anyhow I want to make another team, but what class?

I'm considering

quad-hunters, quad-boomkins, mage/priest team (3 mages, 1 priest), maybe 4 warlocks.

The purpose is basically just BGs and doing something new I suppose.

Opinions please!

I would stick with the caster classes Ive recently been trying out different combos and I'm not a fan of melee. But, im also lazy and thats probly why as it feels like more work lol.

go for prot- shockadins :D

Dont work ... Avenger's Shield OR Holy Shock ^^
