The more character classes the more complicated the macroing.

I'm in the setup phase of my 2 pally, 2 DK and Enhancement shaman team and they haven't run as a team yet, but I'm sure there are ways of setting things up that reduce that complexity.

e.g You decide that you will only use charge as an interrupt, so might bind that to the same key you have for the shamans windshear. Charge will only work if at the right range but it's there.

You might decide that you want it to stop the enemy running away from you so could then put it on the same key as the deathknights chains of ice , or the shamans frost shock. Round robin if necessary.

I love the idea of the warrior in the mix, the thought of hamstring, MS effect and bladestorm in pvp appeals.

The shaman totems for some fear protection and grounding......
