Bit of an update. Priest guy is level 30 now and well...he sucks LOL. Extremely easy to get swamped and die. Hit and run tactics work but don't feel very heroic after doing it a hundred times Hah. Heal spell is inefficient and pretty terrible compared to a heal pot. You'd think with all those points spent and the cast time/animation it should be far better than a pot. Curse is OK at best. Does not work on any form or boss which is silly and outside it obviously rarely hits more than 1-3 mobs.
Fear is not great either. At least compared to most of the combat skills. Anyhow, yeah. Game is a LOT harder playing a Gimp
