Am I doing it wrong?

[Pandamonium]

So I just hit 60 with my first team and I'm going to take a break from boosting to level my priest, pally, 3X hunter team.
Since this is my first team to 60 I'm feeling a little overwhelmed with all the setup I have to do, and also I'm a perfectionist. How I'm trying to do it is to have modifiers for each classes abilities, i.e. <alt>+<shift> for all priest specific abilities, <alt>+<control> for all pally abilities and then <alt>+<cntrl>+<shift> for all hunter specific ablities.

Am I making this much more complicated than is necessary?

(Also note that I am binding the groups of modifiers to buttons on my G500 mouse, I don't plan on pressing those keys on the keyboard for every ability)
