Just FYI. you're a jerk if

You intentionally play champions in normals that are just for wins. (which has no excuse, since the champions that are really the issue are the ones with simple mechanics.) You brag in normals about winning only by being one of said champs (including all top bans).

Just to add to the list of things, besides the fact most of the people who do that are toxic players anyway.

All you're doing is making the game boring for everyone, which is the most toxic thing you can do in normals besides verbal abuse. For yourself: Easy mechanics, and the champs are usually top ban so you're not learning anything you can use in ranked. For enemies: What you're doing doesn't require mechanical skill, so when they lose they can't even honor you for any good plays. The champs like this are all AA's and targeted moves. Worse, for your Allies: They don't get legitimate practice or even a good game because you're taking all the fun out by doing the work.
