I use a similar method(lvl23), however, in a situation of 1 elite and 1-2 non elite, I use an explosive dart on the non-elite. This makes him panic, and not attack, while the explosion will certainly hit the elite; Who I then shoot with a *crap, can't think of name, it does explosive damage, then fire damage over time, as an AOE*. That in turn also hits the non-elite,killing him, and I finish off the Elite with some tracers.
I try to spread out my AoE attacks to hit everyone, and try to maximize the amount of mobs I can CC for a few seconds by making them panic ( or whatever its called, knockback, on fire, ect).
Just my 2 cents of game play. =) PvP is another thread, and holds a way more enjoyable rotation. (Hint: there is none)
