To everyone arguing that the newer stuff isn't just for whales, you're right. It's also for FTP longer term players. But if you started a FTP account within, what, a year? You can't even touch these things likely the Geo TBs are out of play, the assault battle tiers most definitely are, and you sure as hell aren't going to have 13 First Order or Resistance characters at r5 either.
Yeah, that means they have the old game stuff to do, but human nature means people want to be involved in newer things and not be stuck way behind everyone else particularly in a game like this where "behind everyone else" means years behind.
I don't necessarily have a solution, but a new raid or brand new assault battle with multiple tiers is a potential answer.
