[Baron Munchausen]

Well, the Allegiance Subverter is like all the other 'specialty' damage weapons -- there's no defence or mitigation! This is the problem with 'engines only' damage, 'shield generators only' damage, 'weapons only' damage, etc. It's all or nothing in every case.

And crew conVersion is the same. Either your ship instantly joins the other side or it has no effect. If there was a 'shield' of some sort possible, and/or if it tracked unsuccessful hits and increased the chance of success by some factor based on those previous hit, and/or if it took some time to take effect (disabled the ship for a round or two before it came over to your side), things could be much more interesting.
