5 box comp advice needed

Hello guys,

been reading this forum for a while.Now i got the courage to register and ask a question :)

So i'm building a 5 man team for random BGs and occasionally wPvP.No Arena,not fond of it.

For DPS i've got 3 lvl 100 Marksmanship Hunters.
For the healing i have 1 lvl 100 Disc Priest,1 lvl 100 Resto druid and 2 lvl 80(soon 100) Holy Paladins.

Now comes the question: out of the 4 healers which 2 make for the best comp(efficiency,synergy,surv)?

Tried the Disc+RDruid comp and seems like the druid dies too fast.BGs are full of melee and apparently the druid cant survive long.The Disc is quite impressive tho.

So started the 2 Holy Paladins which should add more survivability .So which comp would be better:

Disc+Pala
Pala+Pala
Druid+Pala

Thanks a lot guys!

I would run x 5 of the same class or 4 dk hpal or something tanky. Unless you are in ashran or doing 5v5 you are going to have a lot of issues with movement
