Since there is no limited gacha girls it sounds like a waste of gems. Unless you're really desesperate to get your 2020+ waifu, 1000 FG for one non meta girl is way too much. But it's still better than the old bland premium gacha with nothing else.
Is there something with Halloween stage right now? Since yesterday, I get a lot of raid bosses with the Halloween background. I guess they came from reprint events but it weird if that many people just decide to do the same reprint at the same time.
Btw, I'm affraid enemy evasion is becoming the new meta. It was a thing with Hraesvelgr but now it reached the daily extra event mission. Not great when there is only two girls with bonus hit rate. At least, I don't regret my XMas Blue Lotus at all.
