Here Candace works as our on field DPS since she will be the one doing the reaction. She won't take advantage of Bennett's ATK boost but he is still needed to support Xiangling, while she will have profit from Sucrose's shred.
Yun Jin is a great support character for every Normal Attacks users, exactly like Ayato, since she gives a DMG boost to those based off of her defense. In this team Yun Jin can use 4pc Archaic Petra to furtherly support Ayato.
Zhongli's role is to prevent Ayato's interruptions with his shield. Zhongli has the ability to keep his shield at 100% uptime and shred the enemies' resistances, as well as giving access to Geo resonance.
