Man ill tell u what i hate the ftl i never could get the hang of it. I just keybind my right action bar buttons 1-5 to my f8-f12. The on each char f8 will be the /focus main /assist focus then f9 will be first slave f10 second slave and so on. What this does is if my main dies cause hes my tanking dk then i hit f9 it switches both focus and makes it the larger screen from maximizer. And as well as that i make it so they go from blood presence to frost presence so they pick up the more armor hp and threat bonus.
