How would you like xiao to get buffed
Would you rather him being buffed through stellar reactions, some sort of Liyue buff or something else? Honestly i really like how hexerei work, adding just One passive doesn't completly overwhelm the charachter's kit but if done correctly can be very good, and it also doesn't make team building too strict.
If they add a new set for this type of teams I'm not even sure It would be his BiS, because LNO is so good.
I could imagine his new BiS team to be Xiao(buffed)-Xianyun(buffed)-Zhongli(buffed)-Faruzan, or maybe instead of one of these a new Liyue unit that could get added later on, which I think is possible, since Zhongli is expected to be important in this last part of the story.
I think it would also be cool to be able to use "double" team buffs, like 2 Liyue and 2 hex charachters.
I'd like to talk about even more stuff, but the last important thing I wanna say is his cons NEED to be buffed, make C1 buff his passive w his elemental skill, Idk about C2, C4 could add an atk buff(?) and remove restrictions from C6, if you have any more original ideas I'm glad to hear them
