I, being a Wushuer, personally have no problem with mushu. I (along with other people) have played mushu alot as a newbie. I didnt like wushu to begin with, but the mod grew on me and i started playing it. I feel like mushu is a great way to introduce people to a wushu-based mod. The more people playing mushu, the more of a chance they will try wushu when introduced to it. If you want people to stop playing mushu, you need to show them wushu. Host tournies, etc.. Thats how i started of course.
Moral of the story, people who play mushu are likely to try wushu.
