I use scepter main hand and dagger off hand. Then went 10 in water, 10 earth and am now going 10 in fire. I have great survivability and pretty good heals. I used armor of earth, mist form, and arcane blast. Fire rotation is fire slash, arcane blast then fire tooth and phoenix. This gets you a quick 9 stack of might. Its pretty fun and I'm not near as squishy as I was the first 10 levels or so. All in all I am really enjoying this game as I really liked the first one.
If you are casting all those fire spells then what spells are you using with those water/earth traits (and what talent did you pick up in those lines)? Do you pre-cast the earth armor before soloing mobs?
