You're presuming that Yamamoto would be able to hurt it at all, when it's shown firepower and durability well above Bleach's current paygrade. And statements like "being hotter than the sun" don't fly without concrete evidence to back it up. No more than it did when Yamamoto's Shikai was supposedly more powerful than a million Zanpakutos, yet Ichigo holds it on Zangetsu like it's nothing.Like I said if CC can't beat it, I don't see a reason the rest of Soul Society should not be able to after it's been weaken.
Last of all, we always use the current versions of characters when debating feats, whether a series ongoing or not. There's no reason to make an exception now.
And honestly, our forums would be tumbleweed city if we did it your way.
