I just played a rather mad game of 40K. Dark Eldar won; however, what made it remarkable was how Lelith Hesperax won it for them almost single-handedly. Over a three turn tarpit of an assault, she took out four Grey Knight Terminators, seven Grey Knight Purifiers, a Brotherhood Champion, a Squad of Sanguinary Guard, and Commander Dante. It literally took a Nemesis Dreadknight with sword to get her in the end. I kid you not, it was brutal, and no player was rolling particularly badly.
I don't care what anyone says about her, strength 3 or not, she is a frakking beast in assault and I now know a Grey Knight player and Blood Angel player who agree with me.
