I didn't see anything in the rules for this, but in melee, it just seems logical that a distracted party should provoke some sort of attack.
For example, a character is in melee and tries to switch to a blaster rifle. It seems to me that any fighter would take the opportunity to strike again, or run away.
I would propose that if someone is in melee and distracted, their engaged opponent gets a free action and a boost to a check made with that action. The action could be exchanged for a maneuver to run, or also pull a weapon, etc, but could not exceed the two maneuver limit.
Thoughts anyone? Is this game breaking or totally unbalanced?
