I definitely do think you're capable of being staff. Although you have little amount of ban request, but that doesn't inherently matter too much. Other than that, you're pretty helpful on the server and active. You don't as heated when trolls or some problematic people are on.
As for the mic, that's understandable. It's optional to use it. Previous and current staff prefer using chat over mic. As long you're a fast typer and be able to give out warnings as quickly as possible, then I don't see a problem.
