Character acquisition should require the team(s) for which they are meant

Imagine when palpatine showed up, I had full empire ready (when empire was garbage), was all happy about getting emperor to end the rebel scum, and what happened? they make it rebels to unlock it, so I could not get him first time. They do that so you are forced to farm toons you don't want, and some might end up using money for it. It's a cheap move, but it's a jungle out there as some would say. Strategy to get the max profit from the situation.
