Those are the only good cards for Precision Training, with Find the Weakness being the best. But then you are pretty much playing with just those class cards all campaign. The class can be solid mid game if you rush the 4xp but falls apart late game when Rebels steam roll figures toward the end. It's good when you can get a whole squad to attack but very bad when you are usually left with 1-2 single figures left in an activation after the starting Rebel activation of a round. The
I think someone started a poll the other day on BGG and results are coming in. I agree that Precision Training is the weakest followed by Inspired Leadership. Everything else is avg or very good and the Core 3 classes are still the best (tech sup & MM are getting better with more figure options, sub is always strong since it just targets the Rebels)
