Just a little tactic I've been using for a while (around LVL 48), since I'm not in the most wanted player in the AOE category yet:
Magic Burst charges pretty fast, but I dumped max cooldown on it since I don't have Frost Nova yet and I want to benefit my abyss parties better, since I usually have the best scrolls, enhanced weapons and armor, and at least 40-50 T3 pots that I usually share with the party before the grinding begins.
Anyway, it helps out a lot if you like to grind enemies and you don't (or do) have Frost Nova and Inferno. I am notorious for stealing the aggro from higher powered mages and archers (when they are in the party because my AOE charges every 5.0 seconds with a 0.6 bonus) and keeping pesky monsters off of my healers. Just make you tough enough to take the blows when they come. I planned to reset the after I reach 60, but I'll play around with the spells a bit more to see which one is the most useful. Anyways it's just a practice that's good to have before you reach 60 if you grind like a madmen as I do, and usually I'm the lead kiter.
