Removing AI engineers entirely?
That seems to be a bit...extreme way to solve the problem...
I mean, with the last change the AI engineers went through, the AI actually uses them pretty well; using them to repair more often than not.
It was just in a few cases that they didn't for some reason.
Granted, there wasn't much left that they could repair; fleet ships, starships, hybrids, and I think AI command stations are pretty much the only things left that the AI still has that they can repair.
But still, the AI using repairing those could really help the AI in a fight, or recovering from a retreat.
