Absolutely detest it! Start with class fantasy - our supposedly extremely powerful demonologist summons the weakest possible demons, imps. Oh, and he's so incompetent that he can only keep them summoned for 12 seconds. Ugh, awful. It's just a dot with a different visual, and you have to buff your "dots" after every freaking cast with demonic empowerment.
So, you have a boring rotation, no mobility, horrible target switching, a long ramp up to do any damage and top it off with lame class fantasy. I'm not sure how this even got to alpha like this.
