Ahhh
Cool, but how exactly any of this groups deserved slander? Didn't they succeed in expectations? Gorosei and HK was never compared to admirals and Younko. It was Younko who was called the Strongest, but thanks to immortality now the Gorosei feel like actual threat.
Same thing with HK, there wasn't any hint about them beign strong or compareble to younko and admirals, but now it seems they are compareble.
It is obvious that both Gorosei and HK are stronger then Younko Commanders and that already is impressive. For example, thanks to HK some characters like Cracker and Katakuri will be thrown from Top 15-20 to top 30-40.
