Vanilla Darth Nihilus is too easy of a boss, but giving him Force Death Field instead of just lvl 1 Force Drain makes him way to difficult. He'll sometimes use Death Field 3-4 times in one turn. The power can be really broken sometimes when used by enemies.
While giving Nihilus Death Field does make him annoying sometimes, I do enjoy the extra challenge and I think it suits a character of his prowess more than just drain life.
