Yeah, when I did my MathWing: Accuracy Corrector post on it, I think I came to the same conclusion that it still would not redeem the TIE Advanced.
My main problem with it, is that it significantly reduces the design space. Why even bother adding the System Slot? You might as well just say "Add Accuracy Corrector to this ship and make it 3 points more expensive". And the PS4 and Steele would still never see use.
This would get more people to fly the Advanced, but it would also shift the tactics of the opponent, as no one is going to just leave an auto-hitting ship like that alone until mop-up time. I think it would be worth at least playtesting amongst ourselves, just to see what it looks like in practice.
Absolutely, I am all about playtesting different ideas.
Honestly, with how I use the Advanced when I play (as a durable, arc-dodging flanker, with Engine Upgraded added on), I think I would be more likely to take Sensor Jammer over Accuracy Corrector anyway. The major issue I have with Accuracy Corrector is how it waters down your Range 1 attacks. While this may not be a big issue on say, a TIE Bomber, the Advanced (especially with an Engine Upgrade) is going to be firing at Range 1 quite a bit.
Again, it'll be interesting to see what actually happens. I think a Sensor upgrade slot wouldn't be the worst thing you could give the Advanced. A 0- or 1-point title that gave them access to the Boost action would be a serious pain on this ship. Saving those points for another upgrade would make the ship very flyable, without overpowering Vader.
Just my two cents. And on an unrelated note, I love the Norse rune there, MajorJuggler. ![]()
