Around Christmas, I was banking 800k moe crystals with each rebirth. When Janurary hit, I noticed I was getting slightly below 400k when rebirthing at the same stage. With that, I thought an event ended. It was Christmas, so maybe the developers were giving out some extra crystals with rebirths. I took a bit of time off and when I came back in Feburary, I noticed I'm now getting 123k for a rebirth at the same rebirth point. If there was an event doubling moe crystals, they were either stacking that event with another, or they nerfed the crystal payouts hard in the last few months. Either way, at 123k, I can only level up Codex of Souls twice for a paltry 10% more moe crystals, and I'm at a wall that requires another, higher tier hero than the Toy Maker, badge to break the 1000 level cap. Playing the game so I can farm the in game currency from rare fairy chests so I can possibly save up enough to blow on a chance to get half a badge is stupid. I wasn't making much headway with moe artifact upgrades, but there was noticable progression. I've been stuck at stage 2170 for months, and it seems like the devs are trying to milk their players for cash in the worst ways possible.
