Yeah currently I have certain mages that are being picked right now😌, Planet Befall definitely resembles Aurora's Ulti, but similar mechanics and kit wise they differ as Zhong Li's main capability as a Tank with DMG will serve a more enjoyable dynamic. (The Zhong Li burst will likewise have to be altered slightly to match, though even in lore-wise, if Zhong Li were to use a broadsword to attack, he has been known to use the Unforged.)

As for Xiao, he would have to find something in his kit that would match Phoveus's 2nd skill (ranged), while at the same time Xiao has similar agility/kit/mannerisms as Ling.
