Displaying mastery level in the champion select screen?

Probably a bad idea, but what do you think about displaying your total mastery level in the champion select screen? I think it would be interesting, but at the same time, it'll probably lead to abuse, just like 99% of any suggestion or idea anyone can come up with for this game. What kind of abuse? People harassing you for having a score too low or too high, and even likely to report you under the claim that your account was bought.
