How About People Seeing Your Champion Mastery In Champ Select?

I was thinking about the champion mastery and how I recently got my main to level 5 ( ), as you can see it's a pretty weak champ but I can play her really well and I want people to know that I'm great with her by them seeing my level 5 badge on her when I've selected her in champ select.

I was thinking that it could look like the champion portrait in the normal place (on the side of the screen) and it having the badge (whether it's 4 or 5) on it, like in the loading screen. I think this'll make people trust people with off-meta picks (only if they're level 4 or 5) as they can see that they're good at the champion and not troll in champ select for them to change champion.

I've had quite a few problems with people threatening me to change champions or they'll troll the game so I have to change it or be trolled. But if they could see that you're level 4 or 5 with the champion they might have second thoughts about trolling the game. I can see one or two downsides to this as people threatening others to change roles because they're level 5 with like or and the other person is only level 3 or 4 with or .

I would like your opinions on this as I think it'll help people see that the champion they selected are good with them and not think they're trolling. I've had many people leave teambuilder just because I picked Elise top and they don't believe I'll do good with her (which I rarely ever do).
