For an incubus, the eye thing does make sense lore wise. However, in a player controlled environment, an arena sense, it's a bit at odds with everything. Some chickie fighting for her life, glory, and riches beyond belief, probably won't just stop and go "Hmm. That dude's got some killer eyes, Imma go bang." Frankly, a drill penis would be much more useful combat wise, and then LeeRoy has nothing to say about the whole emotion forcing thing.
