Just because base stat is 0 doesn't mean she will have 0 firepower right after getting remodeled.

Modernizing firepower/torpedo/armor is never a pain. You are drowning in mod fodder. Only AA is harder to get.

Hiryuu is very useful thanks to her firepower (she can reach day cap with just a fighter bomber) and evasion. Small slot should be used for Saiun and three slots of Hiryuu are much better than three slots of Zuikaku.

But yeah, the guide does give off vibe as if Hiryuu was worse and that's where it's wrong, among many other places.
