As others have said, 7* units aren't going to be as widespread as 6* units. The reason (probably) why Aisha isn't getting a 7*/doesn't have one is because she isn't that popular or just doesn't "fit" in the game as a 7*, pointing to the possibility that Aisha will just be another outdated unit to eventually become harshly outclassed by newer units. Well, that's my theory/guess.
