Transports in general are kind of abusable. They're good at releasing troops from an AI world for example, and if you stick them next to your defenses, enemies will shoot them instead of your tractors, turrrets, and ships. On the other hand, I don't want transports to be nerfed because they're now actually worth using to transport things, but the non transport roles for a high hp high shield fast moving ship that the AI can't resist attacking is quite exceptional.
