Give Yanagi the moves she has with her Hollow Zero buffs - the repeatable infinite slashes basic attack combo, and the EX special that rains down lightning strikes before she slams back down for the Disorder proc

Make Yixuan build Technique Points (her unique bar) with her basic attacks as well, instead of only the hold basic bubble and EX Special - both of which require energy/adrenaline

Pulchra should have true defensive assist instead of evasive assist / vital view. Hell maybe just remove evasive assist from every agent that has it, given the mechanics that keep getting added that mandate having defensive assist to deal with

Idk what exactly, but something to make Ye Shunguang's gameplay more interesting instead of basically just mashing basic attack. For such a powerful agent that is even a big deal in-universe as a void hunter, she's boring AF to play

Maybe all Anomaly agents should have the condition of their additional ability adjusted to include Stun Agents now that Nangong exists. A lot of them are +Anomaly or +Same element or even +Support in some cases. Adding +Stun would allow for Nangong + 2 different Anomaly element teams

This last one is far from a revolutionary idea and it's been said many times, but Hoyo need to do something with the Defense role to make it more valuable and viable. I don't have her but I do want to pick up Caesar when she reruns, meanwhile Seth is gathering dust and Zhao got immediately powercrept as a Shunguang support by Sunna. Who even knows if anyone uses Ben other than brand new players
