Is the Musa really this games version of Samurai if so it doesnt really feel like it. On top of that it doesnt really look like it either if anything the Musa feels more of a Mongolian warrior then a samurai. Hell the Ninja seems more samurai then the Musa. This is just random thinking from newbie. But after looking through all of the classes it dawn on me in such a reqard as to if the Musa was really the Samurai class of BDO. 

Its not. Musa is based on the Korean warriors not the samurai. Ninja is their japanese style class both main hand and awakening.
