10 boxing group comp

[FetteredApe]

I'm not allowed to post in the group composition forum, so I had to put my post here.

I am thinking about going to 10 boxing, and was looking for a check on my planned group composition.

I currently have:

1 Prot/Ret Pally
1 Arcane Mage
1 Shadow/Holy Priest
1 Elemental/Resto Shaman
1 Resto/Balance Druid

Was thinking of leveling and adding:

1 Prot/Ret pally (for off tanking and additional buffs) (Or should I do DK? Warrior or Feral Druid?) (Maybe Prot/Holy for the pally for Tank healing on single tank boss fights?)
1 Destro Warlock (or another spec - never played a lock)
1 Holy or Disc Priest
1 Elemental Shaman (more totems!)
1 Balance Druid

This group is all ranged DPS with the exception of the 2nd pally (if I go ret). Is no melee dps problematic? I run ISBoxer and Jamba, and I know melee is possible with IWT etc, I just haven't delved into it. Ranged just seems easier to me... I originally had thought of getting a hunter instead of the balance druid, but I didn't see how it would add much to my caster group. Did I overlook something?

It will take a lot of work to level up another team of 5 to 80 so any thoughts/comments would be appreciated! I'd like to do this right the first time
