Its still a work in progress, but AG Unit frames is starting to bother me.  I have trouble seeing my own health during fights, and I can't figure out how to change the opacity of the unit bars.  My bar isn't green enough, and enemy bars aren't red enough.  Also, I have a nervous habit of toggling "c" to bring up my character screen all the time.  With this settup, my screen stutters during fights if I do this.  I'm sure the rest is just me not being used to it, which includes timing my rotation with CD counters, and I'm just not used to looking at them in the new location.
