It's a real toss up. With Nihilis throwing out a debuff at the beginning of each of his turns, he will gain life from EP lead. He also has good health steal, health, and protection. SunFac is a taunter tho, and when a dispeller debuffs him, RG can still protect my EP. SunFac is much harder to gear, but I have to do it anyways because of his ship. It is such a tough choice. With how bad my mods are, SunFac will probably keep his starting role, but time will tell. I need to crack the top fifty(I'm 53 now), and see how it goes.
