I have PiP enabled so my CTRL+F1/F2/F3/F4 Change my characters out. Assist is off of /party1 so whoever is leader. Little more maneuverability, sorta the same as yours though. I was thinking about making buttons to where lets say button 1 heals Me with lesser Shift 1 does chain heal on me and Ctrl 1 does big heal. And do this for each person 1 2 3 4. Seems like it would get confusing? Setting up and getting use to your UI seems to be the HARDEST part of this. Then its just adapting to what goes down. So your W key is your /follow key too? That seems like it would be better then my CAPS key.
