5-box with many armour types?

[confusedtx5]

With the new RAF groups I'm in the process of leveling (inc a 4x shammy team), I'm actually finding that the majority of my gear is coming from the quests at the start of the instances. since you get the same stuff to choose from for each toon, armor types doesn't seem to be an issue.
Though, if u run 4x shammys then u can always wear leather/cloth. The damage difference isn't noticeable much until around lv80 or above.

Another good option blending your original one and maintaining ranged is:

Warrior (tank)
Paladin
Priest
Mage
Hunter

So you still have 4 of 5 ranged (I like shockadins) but you can as an option go with a ret for some 2H action. Two plates, two cloth and a leather/mail wearer.

I'm currently leveling Warrior, Priest, Mage, Lock and Shaman so I've got a little more variety. Other than most of the caster stuff in the range I'm at (68-74) having spirit on (there's even a quest that rewards a choice of two caster rings, both with spirit) I've not had trouble keeping my clothies at a reasonable gear level. This might become more of an issue at max level, but most upgrades will be coming from J/VP anyway so I don't think shared loot is such a problem. Even if you have a mixed gear group, once you've had the item drop once it is no longer useful (e.g. I keep getting the same mail gloves from the first boss in Nexus). I've got an enchanter in my group so even at max level any unusable items will still serve a purpose.

If I didn't have two already I'd be tempted to switch my Lock for a Moonkin, but that's more about buffs and the Lock's poor dps than sharing loot around.

I'd switch a mage (mine does nice dps though) or the lock for a hunter or shaman to provide more buffs to your group. Hunters are pretty versatile with their different pets and you could keep to Belfs. I've got one in my low level group (40ish) and she does pretty decent dps when I remember to keep her at range, my solo max level hunter also performs well.
