what to do when yunli gets nuked

have to use preservation? my crit ratio is too close to done, i can’t fuck it up for more HP idt. highest level of MoC is instakilling my Yunli with Lynx

wouldn’t this problem be worse with HuoHuo since she can’t give Yunli more HP? is this purely a build issue on my part? or should i be using preservation with her sometimes?
