I like all the elements, but fire isn't my favorite. Berserk and Curse on the Expert are definitely awesome, but I can't find anything else worthwhile. Sacrifice – I don't know, maybe it's good, but I don't use it. Armageddon – I agree, it's great. Frenzy – I don't always use it, just like Executioner. Misfortune – honestly, I don't even know what it does; I don't feel any effect. Minefield – complete garbage. Blindness – I have nothing against it. Fire resistance... the enemy rarely uses fire against me.

P.S. I wrote down everything I could remember. Oh, and Inferno and Orb – I just don't like those spells. They're too weak.
