Is Spell Penetration usefull? Doesn't that just ignore Resistances from you target? Wouldn't it be more usefull to just cast CoE, or should you cast CoE ánd have Spell Penetration?
When going demon: Just pop every cd you have (Immalition Aura, Demon Soul, trinkets) since you'll be a huge target. People get drawn towards a huge purple thing bouncing around between 10 enemies. I like to run in from behind and blow all cd's while Hellfire'ing and Felstorm. It would be more wise to focus on the healer, but it is way to much fun
