I totally understand all your points.

Your first point I would like to address. Would it be a possibility for the Chideta clan to be famous? That way they kept Chen around because he was important as a figurehead of sorts. I was kinda iffy too on how I could make him important. If you have any suggestions I am totally open to them. Also, yes I did draw inspiration from Kakashi when creating Chen.

Your second point is much easier to address. The only jutsu he's "mastered" is wind. The other two it's just that he as those for just in case situations.
