4 Shamans, What kind of healer?

I posted this in the other section, however this seems to be more popular.

4 shamans and I'm thinking of another healer. Arena use of course. Ill be controlling the four shamans. Honestly i was thinking a druid would be best for Hots. pally's get CC to easy when there the only healer. Druid can change forms too. Thoughts?

Like I said before Healing Shaman IMO. Seem to be OP

but why?

have a shaman healing my 4 druids its is good

for a shaman team im not totally sure that another druid would bring that much more on the table, main reason i chose a shaman to heal was after realiseing what more the shaman would bring to a 4 druid team.

for a 4 shaman team i would go for a paladin speced with improve concentration aura, this will give you somthing like 55% interupt avoidance while casting, as well as different buffs BOW or BOK.

I put a decently detailed response in the other thread at http://www.dual-boxing.com/forums2/viewtopic.php?t=2808

We are doing a pally... gives you nice heals with good mana cost so shammies can focus on DPS.

Also can stun so people being cheap and hiding can get a nice DPS surprise.
