The leaving certain keys blank seemed to work very very well. The only other main issue ive found is that I have made a macro to /assist khole wich is my mage. Binding the macro to the T key. and in keybindings making T on the first spot on the top left action bar. This way i can press T on my mage and it will target a mob and at the same time my warlock should assist my mage getting the same target. However nothing seems to happen and if i change the key binding to a different key such as say 9 or 0 it works fine. Is there any known issue with making a binding on the Addon bars (the extra bars blizzard allows you to have via the interface options.) and then assigning a letter to it such as T. I wouth think this should work not a huge setback more so than an annoyance.
