They are almost essentially loot boxes though; even though they have fixed rewards there is 600+ chests, so it’s a needle in a haystack situation. But then they complicate the issue because you can bring more boxes in via Kronika’s time clock.
So whilst it’s not a loot box, it’s a scavenger hunt that requires expendable amounts of resources that are utterly ridiculous to acquire. 1 fatality or brutality to just get a single heart? A chest costs 250 and those have the best stuff. That issue isn’t gone either. And i know they said they’re working on maker bigger rewards, so that’s a wait and see but it still doesn’t sit well with me that the game has made it extraordinarily difficult to get skins I want. And the ones that are found in towers of time have really difficult requirements once you finish the first one per character
