What do people think about this? I've been using mobile repair stations, but I'm thinking now that, given cloaking, Mk III engineers are probably more capable of operating in the middle of a fight. And, without the minute stun time and teleportation, they're much faster if you need to repair a starship that's in danger. I guess mobile repair stations are better on defense, where you can keep them out of harm's way and take advantage of their ability to repair multiple ships at once, but there they seem to overlap with fortresses, and their cap isn't really that much higher.
Am I missing something about repair stations?
