PSA to Bronze Players
This is a special message for if you main any of the following champions. I have some solid advice for all of you, so just bare with me.

If you are in bronze and main any of these champions, I have a valuable piece of advice for you:
PLEASE STOP
Ok, that sounds kind of rude, but hear me out. All of these champions have complicated mechanics in play, and/or require a high level of skill in the game, which you.... 90% of the time do not possess. Don't get me wrong, I'm not calling you bad. I'm just saying that you're making bad choices. Now, I'm not going to break it down for each and every champion, what makes them difficult to play. I'd have to do the equivalent of a research paper to go over it all.
When I see these champions and I'm laned against them, I get excited because I know I can pick any of my mains and have a high possibility of success, but when I see them on my team, I desperately want them to switch champions, because I know that they're not ready for them yet. If I were in high silver (like, Silver 1) I may let them go, but any lower than that, I don't care how many games you have on this champion, I don't care how well you did last game, I don't care about your only slightly positive record with them (yeah, going 7-6-x is NOT a good KDA, even if you win).
I may be hurting myself by saying this and helping a lot of people in Bronze get better, but I just cannot stand these people on my team, especially if they get toxic and tilted when they lose, and blame everyone else for their own ineptitude. Not to mention, if you're bronze, you won't be able to play these champions well, because in Bronze you have no opportunity to learn the things about the game that you need to know in order to play these champions correctly. There are too many distractions in Bronze for you to adequately identify and learn from your mistakes.
Please, put your pride aside, look at your win rate, and switch champions. Do it for your placement in ranked, and do it for your team. Please.
EDIT: Removed Nunu from the list, because the only thing that makes a bad Nunu is when they try to counter-jungle without knowing how, or going support Nunu and feeding hard.
