User blog comment:Dettles/How common is Haki in the New World?/@comment-174.92.92.238-20130421013908

As you have stated in your comment, Haki in the NW is the equivalent to DFs in the Grand Line. That being said I'd believe that types of Haki vary in rarity in the NW as does types of DFs in the Grand Line. I don't see it as everyone having Conqueror's Haki, but rather a small minority. Armanent Haki and Observation Haki are probably par in the New World when it comes to rarity. Similar to DFs in the Grand Line, it's not every DF user was a Logia type, only the really powerful fighters were Logia types (e.g. Crocodile, Enel, Admirals, Ace, etc.). Paramecias and Zoans on the other hand were far more common in the Grand Line (e.g. the 11 Supernovas, Buggy, Rob Lucci, Dalton, etc.). So chances are really powerful fighters in the New World have Conqueror's Haki, whereas the average New World fighter has either Armanent/Observation Haki or both. And just like DFs, mastering your Haki to a certain degree will probably make one a better fighter in the New World (just a thought/theory).
