Is it the only purpose of Battle Furry power, to prevent my character from being MCed or does it have another use?

If a character is b2b to a an enemy character can it been given a ranged attack action?

I'm sure Battle Fury is good for other stuff, but I have NO idea what besides the MC thing.

And if you have Battle Fury then you can't be given ANY Ranged combat action even if B2B.

Just to confirm, The figure w/ Battle Fury cannot make a ranged attack against another figure, for example Hellboy when he hits his BF spot has a 3 damage and shows a 6 range, but cannot attack anyone from range and must do it B2B. They can however be targeted w/ a ranged attack.
Battle Fury figures cannot be MCed and cannot be carried, thereby making it the only power w/ more negatives than positives.

But could you outwit the character that has battle furry so they could use a ranged attack or be carried?

But Outwit says "target opposing character" so I don't think you can use it to allow you to carry your own BF figures.

You cannot outwit your own characters.

The worst drawback to BF on a Super Strength figure is the loss of the ability to throw an item. Atleast, I think that's the worst.
