So, I'm now at a point where I should start thinking about tactics and beating higher level content, but I'm unsure which direction to take and what girls are good anymore. Is Kerria still a staple, for example? And I gather that debuff has been deprecated? Should I start working on putting together a super counter team or get someone to strengthen the existing team?

I now have the legacy 6* ticket and enough crystals to RG someone. Should I save the crystals in case RRose is rereleased in a sealstone or something?
And who to get with the 6* ticket? Ordinarily, I'd pick Black Lily, because she's a woobie, but I should probably aim to get as strong as possible as fast as possible first.


Right now, I have just a random team thrown together from girls I have been able to get:
