My main keybindings (1-6 + shift + ctrl) do not make much sense. They were just placed pretty random. Used to it now, so no point in changing it d:
I usually use G's for CC. Like:
G\ Psychic Scream
sG\ Shackle target
cG\ Shackle focus [will make target focus if none exists]
"<" (on a danish keyboard), the button next to shift is used for dispels.
<\ Dispel target
s<\ Dispel self
c<\ Abolish Disease
Got Mass Dispel on mouse5 (a button on the side of my mouse) for quicker and more logic placement.
Ventrilo speech is bound to the mousebutton next to that (mb4)
