So my understanding of the Han Solo and Gunner/Luke Skywalker interaction is that the Gunner allows a second attack if the first misses, and Han can choose to reroll all dice in either (or both) of these attacks (except for those dice which have already been rolled).
Firstly is this right?
And following on from that, is there a whole lot of point putting a Gunner on Han? I've been sold on the usefulness of the gunner (ie in clearing away the defender's evades and focus tokens with th first attack), but isn't it better 'value' on one of the other Falcon pilots as Han already gives you a second chance of a better roll?
And finally, does Marksmanship then tip the balance back in the favour of Han with the gunner, in order to maximise those focuses and crits?
