because like it was said before, just doing ptl + advance sensors or w/e doesn't really focus much on his ability and could be a cheaper E-wing
I don't think this is really true, you just have to accept that his ability is something you'll use in the right situation instead of defaulting to making two attacks. Let's say you have a nice range-1 shot on a wounded target, but there's a good chance that they'll get away next turn. Corran has a good chance of finishing them off before they can try to get out of arc, especially if you have FCS or didn't have to spend your focus earlier.
Also, don't ignore the value of PS 8 on a ship that lives or dies by its ability to dodge arcs. Getting to boost/barrel roll after everyone else has moved is an incredibly useful ability to have, even if you don't use his special rule very often.
