click to move and interact with target is your friend.

Look at the thread describing how to use it with melee guys. All you need to do is face your target with your main and click you assist button and all your toons turn around and run back to the mob.

This ! Really. It made a huge difference last time I fought her, now that I know about that trick.

One press on my "everybody assists focus" key, one press on my "everybody interacts with target", and everybody is running towards her, starting to beat her up, ready to cast. It makes the figth amazingly easy.
