I had this problem with my "Necromancer" Elf, which is Inquisitor with Necromancy, Geomancy, and Zombie Talent. I could heal myself with poison, but had little damage compared to ice/fire and virtually no CC. The long cooldowns on the spells didn't help much either, so enemy damage would just outpace my heals and poof, dead. What ever happened to low level summons? We all miss you guys!
