The elemental shaman shifts to heal gear and heals whenever the paladin has to tank. There is also a lot of shuffling groups to take full advantage of heroism, and to spread the shadow priest love around when needed. Gear as a whole is probably about half hyjal/BT gear, and half from T5/ZA/badges etc. The rogue has four piece T6 but does not get windfury, which is something I wonder if we want to make happen, not that I really need to complain about a setup that does the job.
