And with the new Gozanti TIE pilots, I think both Scourge and Chaser deserve some attention, as they work much like Backstabber/Mithel or Night Beast respectively. Scourge, like his earlier counterparts, has a condition that can lead to him getting an extra die (one that's arguably easier to achieve than the other two), while Chaser (like Night Beast) can essentially have a poor man's PTL. Could even throw the rarely seen Targeting Computer on either of them, negating the need to have Howlrunner along.
Oh certainly! And that's before we get to the TIE/FO Fighters. Look at Zeta Leader!
I think what people tend to forget is that the more expensive a ship is, the fewer ships you can fit in your list, the more it _needs_ to do damage _every_ round. And yes: the easiest way to design that is to toss more dice. 29 points-before-upgrades Darth Vader was simply not ever going to have a hard time justifying himself at 2 dice. He simply won't hit often enough. I do think there's a case to be made for Accuracy Corrector + Juke on Darth.
