With the changes to power weapons, I'm considering throwing some Deathwing into my BA force. Hydras are also appealing choices, given you can stick an Officer of the Fleet in your requisite HQ slot. I've had a few funny, but awful ideas, and overall I'm not sure my BA list will benefit much from allies. Some tough choices on what to cut, especially if Dante's weapon goes to being a power axe (it is an axe after all).
