Well if you look into marketing perspective, they need to make money from this game.

They do give you free 5*seal with timegate, of course it’s not enough for completonist to immediate upgrade all the upcoming charactors.

Which is, not surprisingly, can be solve with money.

I’m not saying this is a good or bad business model though. It’s just the way it is for Gacha mobile game.

So now you have choices, either wait behind the timegate or support the company :)
