lvl 80 teams
My pala + 4 shamans team is all in T9 or better gear.
My warlocks team has been just geared with pvp gear except the weapons and trinkets... something I will sort this weekend.

lower level teams
my lvl 70 druids team will level to 80 as soon as I finish my warlocks team gearing and icecrown quests with them.
my priests team is waiting for the druids team
my mages team is waiting for all the other teams

So far the teams will have the following uses:
pala + 4 hamans --> pve
5 shamans --> pvp/pve
5 warlocks --> pvp
5 druids --> pvp/pve Aiming for an useless arena team with 5 resto druids just to piss people off being unable to kill me.
5 priests --> dunno, could be fun in pve and could use these as healers for some content where resto shamans don't cut it.
5 mages --> pvp
