Well, i was also thinking of letting my characters be able to dodge bullets, though it would be more of a "belly-dance-dodge-while-keeping-your-eyes-on-the-gun's-muzzle" that allows to dodge a significant amount of what you're fed, yet takes a great amount of concentration and implies direct eye contact with the opponent. Morever, dodging fire from multiple arms would increase the strain expotentaily. That must be legit for a high-intermediate character.
