So Im curious how Shamans scale post 70.

Im firing back up some wow boxing and had planned on doing 1 pally, 4 shamans again with RAF. However, my brothers telling me that at 80, shaman dps doesnt scale so well and that they are rather low on the DPS meters now. Before I spend the next busting mine and my brothers arse off we want to make sure we can do end game instances.

I plan on making several teams over the next 90 days, but just want to have a good team to start with.
