You know, just last week or so there was another official Naruto game in China, very much like this one, that had a huge tournament with monetary rewards. The champion of this tournament played as Dosu in several of his matches and rounds, and he even used him in the final defining championship match. Dosu was literally an essential part of both the game's tournament, and the winner's path to victory.

Now compare that to Naruto Online, where we're getting Haku dressed up in a noncanon outfit before Dosu is playable at all, despite Dosu being already part of the game.
