The one thing that I believe I'm definitely going to have to do is change my entire playstyle by stop using my keyboard keys for movement and strictly use the mouse. There were several time in BFD where all five of my toons would get frost trapped and the mobs would move behind me. At that point, I couldn't move my main into the direction of the mob in order to have my hunter's target it. If I stop using my keyboard keys for moving the main toon then I can utilize them for spinning all of them around as needed. That's going to take a lot of getting used to though. But in the long run, I believe it will benefit whatever type of team I put together.
I use the WASD keys and have the arrow-keys set up for this. I only need "turn left" or "turn right" set to the arrow keys and so my toons can circle into any direction by pressing those keys. No need to do it via the WASD.
