That does look interesting. I don't really understand why Arcane Stability is necessary in PvE though. Theoretically, you shouldn't be getting hit in a raid, so you shouldn't need that talent, right? The Incanter's Absorbtion talent with Frost Warding looks pretty cool though, although I don't typically use the warding spells, so it would take some getting used to to have to remember to use those spells. Is that spec only useful in Ulduar or will it be useful in other raids or heroics too?
