Another nerf?

The reward dungeon got nerfed. Can't infinitely roll the mini collab gacha anymore. Sealed Gate's strong enemy levels used to go up to 6, now it's up to 9. Seriously, what does the management of this game want to do? They don't even seem to want to celebrate the anniversary, they just keep making things worse, and they haven't added a pity system to the gacha (for the regular Waipo gacha). It's over.
