Why people don't want to support? They get no support
Nobody respects the support. That's the problem. It's not like you don't have an impact on the game cause you really do its just that hardly anyone recognizes or even seems to understand how a support works (then again I'm in bronze level). Just today I had a Lee Sin call me a noon cause of my k/d....I was 1/8/12. Early game you have to fight your ad campaign to get relic shield procs, or they won't come with you to ward, or cone with you to destroy a ward. They won't help you out a bit and yet they'll flame you the second you make a mistake. That's why no one wants to play support, it's a role with a lot of responsibility, large champion pool, and complex mechanics, but nobody cares about you.
