Just dont have too many abilities on the hotbar.. With WoW build, you could go with frost nova + 3 buffs (familiar, force weapon and energy armor) and then explosive blast rightclick, leftclick black hole perhaps?
Try it Might need a bit of tweaking to work proper.
EDIT: and oh.. You suck :< haven't found a WoW yet....
Glad to help. I usually run MM if farming mats, due to EB not really being needed for lower T-lvl (except to clean up trash as you run past, which I have my trash mob setting at 6 btw), but higher T's I run blades...
