So in our limited little meta, we haven't come across Gunner very often. Last night, playing Heroes of the Aturi cluster, one of the TIEs had the Gunner ability and shot at my friends A Wing. the TIE scored two hits, and my friend said "Well, now his gunner ability won't work".
I said "Nah, they're not actually 'hits' until the compare dice part of the attack. If you evade them, then he doesn't hit you and his gunner will trigger so he'll get another shot".
He was pretty certain it worked the other way (you went from the initial attack roll, regardless of the actual outcome of the attack) and I was pretty sure it was the other way (it only becomes a hit if it's not cancelled out by evade dice/abilities).
Thankfully in the end it didn't matter so there were no hard feelings, but I told him I'd follow up on it and figure out how the card actually works so we know for next time how to use it properly.
So, how exactly does Gunner work? And is there a page reference or FAQ that you could point me to so that I have something concrete to use as supporting evidence, rather than just 'some guy on the internet said so'?
Cheers in advance.
