Some people like to point out that to have an operable turret there is an implied gunner already aboard the Y-wing. This implied gunner is removed when the BTL-A4 title is applied.
I get that, but I say that the "stock footage" implied crew member simply represents a standard being without anything cool to add to the fray.
The crew member upgrade slot, when used, represents a person 'above and beyond' manning the second seat. That person brings something extra to the table, and is represented by a crew card and a squad points cost.
Therefore, saying "The Crew Member is Already There" or "The Default Y-Wing is the BTL-S3" doesn't make sense to me. Clearly the default YT-1300 also has someone manning the turret, even if you don't spring for the extra points cost for adding Luke or whomever.
All this is also why the BTL-S3 Title would have to be 0 points, as it represents what they should've included from the get go, in my opinion.
