So I have some questions about this game's idea of progression.
What exactly is the expected rate of powering up your nikkes?
Is the game just designed around the player always being red numbers and getting walled by various bosses or cheap mechanics?
I know its a f2p gacha game so they expect you to spend money but is the game's primary mode really this poorly held back by the passage of time or the willingness to spend money to move forward?

It feels like every time I pass a wall I do progress quite a bit but then I'm just stuck for weeks until I do it all over again. There also aren't enough mats to go around unless they expect me to only invest in like 7 units or that I buy shit from the cash shop.
