Make it so you can't ban preselcted champions

Pretty much what the title says. Here are some examples:

1. Too many of the blind or retarded people saying "Omg, sry didn't see. I was watching Pewdipie on you tube!1!"

2. When you get the remade team that bans your champion because one of them wants mid and you to support.

3. The person who had a bad Yasuo, Irelia, Vayne, Riven or some other champion and bans it, even though you main them.

4. The person who thinks your champion is a "noob" one, troll or just doesn't want to have that champion on their team.
