User blog comment:D.Dragon123/Why Haoshoku haki is useless./@comment-4754162-20130115015035

My thoughts are as follow:

1) I agree that upon entering NW waters, HH (CH in your terms) may lose its effectiveness in "knocking out people with weak will power" because in NW, only the strong (physically, mentally or ability) should be roaming about here and there. However, back then when Shanks visited WB, his HH knocked out quite a lot of WB's crew, and what's more that ain't some ship, its the Moby Dick, WB's flagship which supposably not any of your average Joe crew member can easily be on. Therefore, should I conclude that WB, THE YONKO, has a (number of) weak (willed) crew (not referring to the commanders but the crew members in general) or otherwise Shanks HH is even MORE overpowered than I initially thought?

2) I don't agree that HH's one and only usage is knocking out weak willed people, in my opinion that is just one of the ways to use HH. Think about it, KH can be used to detect presence AND somewhat gains the ability of foresight. BH is mainly known as an armor type, used to defensive purposes but then can also be used to bypass logia's intangibility and also imbued into projectile weaponery (offensive). And more recently, creativity stepped in and innovated the Koka, seen with Luffy, Smoker and Vergo.

What I'm trying to point out here is to NOT assume the "knock out" effect as the sole purpose / usage of the HH. Its like saying BH is only an invisible armor aura and that's about it. I think there should be other ways to use HH and its these other possible ways that people are seen afraid in the potentials of HH user.

Good blog with a debatable content.
