Support players and rank issues.

Hey, to start off I'd like to note a few things, I am not a native English speaker so pardon me in advance for any errors I make. Secondly, I am not someone that spends a lot of time on fora, so I have no good indication whether this has been asked before or not.

That being said, I'd like to get into it.

I am a support main, I enjoy playing champions like Annie and Sion in the support role (some might call it troll picks, but I got a 100% winrate on those 2 champions this new season in ranked) and that often means that I get tons of assists, a few deaths here and there and a kill from time to time (you know how it goes). Now my problem is that whenever I try to look at my score after a game, the fact that you play a champion in the support role is not taken into account. For example, I just finished a 9/3/15 annie support game where I got an S as rank, this is because the game assumes that an Annie with 9 kills is a mid player, not a support. Another example is a game with annie I had before the previously mentioned game, where my score was 1/4/10 (also a win btw) and I got a C+ rank. Now this is just plain wrong, I played my role well, I gave my life a few times to make some flash engages where I'd stun 2-3 people that we could burst down and make it so that we could push objectives for the win (pre 30 minute win).

What I am trying to say is that now with the dynamic queue it should be a lot easier for you guys to implement a new grading system for off-meta support picks, because this is not very encouraging towards players like me who try to do their own kinda thing in this game to have fun.

TL;DR: I plead for Riot to make a grading system for support players that diverge from the meta.
