I'm still undecided, y'all. Because if the fear test is a perfect, you would accept the hatred to gain the bonus, and the fumble would mean the models are so shaken they can't act. So I feel there has to be a penalty for failure; losing one action and HAVING to go Berserk, or success, remaining at your current DEF and being able to go Berserk when you want. It just seems balanced. Otherwise, why would you have to DECLARE you're going into a berserk state at all? You could have your unit go Berserk, knowing a fear causing model is approaching, and not have to make the roll, but getting to declare it after you've failed the save just seems cheesy. I'm hoping to somehow rope Thom into this discussion.
