Riot, wtf?

So, I'm a support main. I enjoy support. I find it interesting riot is willing to offer ten more champs in the free rotation that can be played in the in the support role. I always que for primary support, because as I said I enjoy playing the support role.

So Riot, if you are so in desperate need of support players, why do you insist on placing me in games that is not my primary role which is support. You would think if someone is queing for primary support, they would get it, because apparently its the role everybody loves to hate on. Over the past few days, I've been constantly getting put into my secondary role which I find annoying, not because I'm not getting the role I want but because Riot is going out of there way to try and get people to play support but when you even try to play it you just get thrown into another role.

Please fix your terrible matching making system/autofill crap. If you can't even place a person into a game who has support as there primary role, which you have shown us that you guys are in desperate need of support mains, then clearly there is a problem with the system.

(PS, first time making a discussion, wasn't sure if I should put it into Gameplay or Client Discussion. Sorry if it's in wrong area).
