Imperials lack an exclusive upgrade type, like illicit or the various astromechs, and it doesn't even fit for them to have one. Upgrade types are ship specific, and the imperial doctrine considered numbers a greater advantage.
What this results in however, is the lack of an imperial niche that is supported by upgrades, available ONLY to imperials.
Problem is, XI waves in, it is quite hard to retroactively give most imperial ships access to something like that, and even if they started doing it now, the majority of imperial ships would be without it.
Another issue is lore. Rebels had more capable craft generally.
BUT. There is one thing Imperials are consistently better than most rebels, and that is training. They are the ELITE. Even the lowly TIE pilot is a skilled ace if he survived a few missions. They don't have the luxury of shields and armor. They rely on their skills alone. They are better trained than the rebellion, or indeed scum, on the merit of them having actual training facilities and so on.
With that in mind, I present to you a Universal Title card.
What do you think?
