DPS/Heal/Tank, idc. I'm comfortable with just about anything, as I'm sure at some point I've done so in the past. I ran Naxx10 with another boxer back in January/Feb, so I'm used to heal/tank/dpsing as necessary; being used as a follow focus (i.e, saftey dancing). In 25s, I've mostly filled the dps slots, as in my old 25man guild our dps was always lacking so I've run melee (DK not pally + 4 elemental shamans).

If you need a healer, I'd rather run my pally holy (still building a healing set) and keep the shamans dps. I could even run holy pally/resto shaman + 3 elementals if necessary, as I did that back in the BC/ZA days when I would run double healer +dps.

Gearscore wise.. meh, I have no idea. I'm sporting all the Conquest stuff on my team (pally has some holy ToC drops, and going to use all my conquest badges now for holy items) and based on imba, I'm "set" for Ulduar content.
