That could work, but would anyone want go though with the fight after they know they'll lose - as opposed to rolling and writing?

Would a roll then write work better under a roll-post-roll-post system? So it's not so much that the battle would be pre-determined, but rather the action needed is. 

A dice system could be as simple as a needing >/= X to land a hit and so on, could it not?
