In light of the recent T-70 X-wing release:
Its the first time we have now Autothrusters on a 2 agility ship. So I assume AT will trigger more rarely because of it, is it still worth it? I would say yes absolutely. But what are the odds? Is there a big difference of AGI-2 vs AGI-3 autothrusters?
I think a T-70 with R2-D2 (or similar "health droid") would also benefit from an additional shield upgrade instead of the autothrusters.
PWT are seen more rarely, but TLT are in the upswing,
