Can you provide a source to this basic rule?
It's only shallow because your favorite characters have no counter to it, I don't like haki or devil fruits, can we remove that from the discussion too? How about we just equalize AP, durability, speed, range and intelligence to make it really fair?
Many iterations of Superman and Hulk have very strong soul resistance feats so they'd withstand having their soul crushed, Saitama and Doflamingo do not so they are victims, this is how hax works, you either have feats saying it doesn't work on you or you get folded by it, Bleach is not alone in having this.
