At the moment, I feel like I'm missing something when it comes to a DoM's AoE spells. They don't seem to cost more MP to cast, they don't take longer to cast that I've seen. From what I can tell, the only issue is increased hate while in group combat. Is that really all there is too it, or does anyone have more information on making a spell AoE vs. Single target?
I've also noticed that while soloing, if I use an AoE damaging move to kill multiple mobs it does terrible terrible damage to my XP. Killing a mob with AoE on the entire time gave me a whopping 18 XP. Another mob I damaged half way with AoE spells, then turned AoE off gave me almost exactly half the XP I should have. I don't have enough experience in groups yet to determine if my AoE support spells such as Cure, Stoneskin and Shock Spikes were hurting our or my XP.
