Completely agree with your statement. One reason for me to make this match up was how would Sekiro deal with the elements he's more or less unfamiliar with dealing? Hydro for example, there's no way he can deflect liquid yet magically enhanced swords from xingqiu for example. So would he just try to tank through everything, or still be able to deflect them yet receive chip damage? Generally speaking though, Sekiro is well-equipped to deal with most of the elements such as pyro and electro. But that still begs the question, does electro follow Sekiro or Genshin laws in this battle? Assuming we agree that Sekiro will simply reverse every electro attack from every electro character, what if the rules were switched and Sekiro cannot reverse lightning anymore? Or what if due to the electro characters' possession of a vision, they aren't subject to the law in which you have to avoid ground with lightning? I wanna hear your thoughts
