Good examples of what you're saying, Tie Pilot, is the Y-Wing and the HWK-290. Stat line is ok for the Y-Wing, pretty poor for the HWK. But both can do things because of their abilities and/or upgrades. Nobody laughs at an Ion-Turret Y-wing, or a blaster turret on Kyle Katarn with a recon spec and title on the table because they're 'statistically poor.' They have good abilities/upgrades.

Those are bad examples for the point I think you are trying to make. If you look at the numbers on both of those examples, you'll see that they have decent jousting values for ships with turrets. The Y-Wing with an Ion Turret and the BTL title ends up with a really high jousting value.
