another problem with r3 is that it doesn't really work against "a lot of academy pilots"
a single evade isn't going to last against all those dice
basically, for all the **** hoops you're jumping through, the result is incredibly underwhelming to boot
you'd be better off changing that focus to a hit and hoping an academy pops before it fires
this is also true of basically any high PS ship shooting at a lower PS without the benefit of incredible defense token stacking + palp
No astromech is really going to do well against "a lot of Academy Pilots". Yes, I said it, but I mean that it would get use against a number of opponents. If you are stuck in front of all of them, it doesn't matter what your astromech is.
The thing is.....if take a TL and then re-roll and get an eyeball....you can't take the Focus. Yes, it's not a huge chance of it happening, but it's pretty powerful when it does.
