Is this a good build?
Has Anyone play a swam of Alpha Squadron with Autothrusters?
No... the lack of re positioning shenanigans and/or token stacking makes them way too fragile. You'd be better off running four Sabers with PtL, which also wouldn't be any good.
4 Alphas with Howlrunner is interesting.
It requires a LOT of skill and practice, though. But it's incredibly versatile.
I've tried it a few times; it's fun!
