I'd probably have picked a souped up Soontir Fel myself, as Fel always feels good to play.
However, Darth Vader and the Tie Advanced has many perks.
For example:
1. Not stressing for Double Actions
2. The 1 Bank
3. Built in TL + F (Fel becomes less defensive than Vader if he takes Target Comp)
4. Outmanuever lets you tell C3P0 and his buddies in the Falcon where to put it (can't use C3PO if you roll 0 dice)
5. Vader is the same or better defense for 1 less pt (Fel + PTL + Shield + Hull = 37, Vader + Engine + Outmanuver = 36)
Of course, Fel has plenty of perks as well, that I don't need to tell you.
Overall, I'd say this build might be slightly better vs B Wing and Falcon squads. However, Fel will do more damage to 3+ Agility ships like Phantoms, Ties, Interceptors. I suppose THAT is where HLC Brath comes into play, after all.
Exactly. Because really, 4 attack v. 4 evade is actually statistically still slightly in the attacker's favor. And the Phantom that I did face got positively lit up by it. True, the lucky kill did go to the TIE, but Brath's 4 hits and the Phantom's 2 evade results were actually pretty close to the regular model of what you can expect to happen (4 attack dice w/ 1 reroll and focus). And I've also come to find that repeated k-turns are actually a really good answer to the Phantom's maneuverability. In an open field the Phantom can choose to decloak and move anywhere to try to skirt close and outside your arc, but in practice this has rarely been possible in a real game with other ships and asteroids so long as the Defender player is smart enough to lay their asteroids correctly, and to pull the engagement into the rocks.
Today I ran an excellent match against a phantom squad, 150 points. Rexler and an Onyx squadron were part of it, with an Ion Cannon and Jonus flying together. The Jonus Rerolls allowed the Ion Cannon to tag a cloaked Phantom. He lived for three more rounds but was never able to decloak or fire again thanks to strategic positioning of my ships. Rexler finished it off handily, landing 3 hits when it only needed one. Kapoom.
And Phil, I know you haven't gotten to play me much but I've played Soontir into the ground. I know very well he's a great ship and arguably better than Vader (or rather, just as good but in slightly different areas), but I've just wanted to move on from him to other things. He was starting to feel like a crutch.
