Why change the crunch? They intentionally created it.
You think they DON'T know if you stack 500 kyro's in Mon Mothma for example, or 1000+ into the bad batch that it's NOT going to create a crunch? Or that if everything that requires a lvl 3 carbanti's going to create a gear crunch when you hand out level 4's like candy and never require them? Or that 90% of the gear handed out in tank rewards is basically useless..
The know, and they built it in to try and force you to spend money. It's not rocket science. If it wasn't getting people to spend money, they'd look for other things. It's not changing because it's making them the money they want.
Does it suck? yes. Do they care? No.
