I just got black swan as my first limited five star (I also have gepard) and ive seen a lot about how she is basically a kafka teammate and she really wants Ruan Mei and Huohuo, but im wondering which one of these is the priority target. Im assuming its not exactly like in genshin where its off fielder/support over on fielder, because theres no on field, but still my game knowledge is pretty limited as of now, which is why im suspecting Kafka.

I also understand that it lowkey doesnt matter because Ruan mei and Kafka will literally rerun in half a year earliest, so its probably huo huo regardless, but im also wondering if its huohuo for that team, because black swan and Kafka want the energy and potentially skill points depending on what huohuo actually does) and if Luocha is BiS in other teams.

For now im using Black swan and Sampo because I didnt get guinaifen yet (im lowkey a man hater jk jk which is why I wanna use as many non men as possible) and Asta because I heard shes good for BS because she wants atk and speed (i dont understand how speed works or rather what I do know about it doesnt conclude as to why a unit would want speed in general rather than a very specific amount) and Gepard because he has an aoe shield and doesnt use skill, if anyone takes pity on my team building attempt and can give me better advice depending on what I have and what I already know.
