The issue with the cost of Autothruster is that it's simply too easy a decision to take them.
Consider the modification slot on Jake Farrell. You can choose between AT for 2 points or Shield Upgrade for 4 points. In every game, with or without turrets, Jake can get AT to proc and a save a damage. If he makes that work 1 time, AT is a bargain over a shield. In games against turrets, AT is orders of magnitude better than SU. The decision on the mod slot for nearly every ship that can equip AT is non existent, you take AT.
That's the issue. Decisions regarding upgrades should be comparably difficult. With AT the decision is far too easy. IMO, that indicates a flaw in the price of the card and or its ability for the cost.
The cost of AT should have been high enough that, at the very least, a Shield or Hull Upgrade is considered over AT.
