I boxed a druid for tanking, warlock, mage and shammy x2. Also tried a spriest in the mix.

Since the druid was for tanking, I had the normal bindings on that one. The mage would just frostbolt / fireball. Shammy some simple lightning bolt and the warlock specced for destro, since keeping up dots on a slave is really hard to manage. Update == DPS. So destro was just spam the shadowbolt and dps would be fine. The spriest was not really giving what it should give. I had it on a flay flay mindblast castsequence. So the micromanagement was not too hard. But then you miss out on the optimal dps rotation of keeping CD's up for SWP, SWD, VT and VE.

So it is not optimal, but doable. Just keep it simple and build on that. Don't try to use all abilities untill you have a set that feels really natural and gives the room to see all that is happening on your screen again and then start to expand. It's just like driving a car for the first time. You don't see further than 3 yards infront of the car, untill you get that natural car driving feeling. The more you drive the more further you start to see.

Im for one am a big fan of the Keep It Simple Stupid principle : )
