If they made the Narga weapons weaker, they would be completely useless without Sharpness +1. Really, the only options they had for balancing the game were: a)Nerfing the boost to raw that purple sharpness grants, or b)Removing purple sharpness altogether. Obviously, the developers chose the latter. And it worked, there's really no one type of weapon (as in, one monster's weapons) that is overpowered, as Dobo, Green Narga, Tigrex, Black Tigrex, Amatsu, Jinouga, Alatreon and Deviljho weapons are all frequently used at top tier, which never happened when purple sharpness was available at high rank (Narga/Tigrex in Unite, Deviljho/Alatreon in tri).
