Eye of the Storm doesn't strike me as a bad idea in general (although, what exactly do you roll?) but it seems, strictly speaking, worse than the Battlebabe move Merciless. As I read, it it's +1 harm sometimes, versus an existing move that gives you +1 harm always. Right?
And as others have said... Battlebabes aren't useless when the shit hits the fan! Like, you've got Ice Cold, you aggro someone to surrender and get 10+ (which you'll get better than 50% of the time, assuming no interference), they either surrender, or they suck however much damage you've got pointed in their face. That's up to 5 damage if you're packing a big hi-powered shotgun, which is pretty much a messy death for any NPC, and a very bad day for any PC. And if you add, say, Perfect Instincts for the bonus when acting on a reading of a sitch, you're actually not that bad at seizing by force when you have to, either, and practically unstoppable at acting under fire. And there's Dangerous & Sexy, which lets you tie down the opposition's greatest threat with just a look, or Visions of Death, which lets you just outright say who lives or who dies...
What moves did your group's Battlebabe take? How was (she?) using them?
