I'm level 24 so, Assuming pet is up: Agitation Send in pet Let him build some aggro DOT like hell Spot heals Occasional HO with Dust Blast or just a regular Dust Blast Re-apply DOTS Spot heals Finish him off. Probably could be more specific, but at work and can't stay on forums long.
Single mob: Agitation Pet attack Static (yes its grey but low and behold it still does damage per tick, and lowers reistance...) Bludgening Siesm (yes even on a single mob) Reapply Static and Bludgening as needed. Depending on the mob I sometimes nuke also by alternating Lighting and Dust. Then tap my pet after the fight for faster power recovery. If I must "pull" the mob replace the first 3 with (however since my pet does not aggro kos mobs even when fighting on my behalf, I rarely "pull" mobs, i just keep my distance): Agitation Static Pet attack Petrify Thing are basically the same for 2 mobs, except I keep one rooted at the start until my pet builds a little hate then have him switch targets (which sometimes happens automatically when root breaks and the mob begins to pummel me...) I try not to engage 3 or more mobs currently unless they are far below me in level/strength. I have done 3 greens, but I'm too lazy to be that active. I would rather let the dots do their thing. Don't fall into the trap that just because spell is grey it is useless, static has been grey for a couple levels now, but amazingly it still lands, ticks away damage, lowers resistance and is cheap on power, useless ... not even, underpowered ... definately.
