How the F*%$ do people STILL mistake their lanes in this game?

It literally tells you your role in BIG FLASHY LETTERS at the beginning, AND shows your icon on the map! What the hell is wrong with you guys? Can't you read? Is that too hard to ask for you to freaking read? Just had a player take Soraka even though he got top lane. I'm support, so I pick Darius because I figured if he is making a mistake I could rotate for him.

Turns out he did. So i rotate top, but I am already at a huge disadvantage because 1.) I am a support main. I know support stuff. Bot lane champion abilities. Good warding spots, good support items to buy. I do NOT know these things about top lane. 2.) I have support Runes and Masteries. I have no damage built into my R+M. 3.) I already purchased my support items, I am now at a gold disadvantage and level 1-4 farming is even more difficult (that is my fault I should have waited until we figured it out).

I don't care if you choose "Fill" and if you think that it is essentially support anyways. Pay the hell attention. Even if you already know your role STILL pay attention. There could be things going on in chat, ban prefrences, prefered champions etc. This is ranked people can't you take it a little seriously?
