No one plays support anymore

I've been playing team builder since it came out and playing league for a few years now and there is one major thing I've noticed is that no one wants to play support anymore. this is for good reason because the negatives of playing support are greater than the positives. when you play support you get yelled at by every one else on the team because you suck and don't have any kills but if you get kills you are bad because you KS. League has glorified kills to the point where no one wants to help they just want to get kills. I play a lot of support but I don't have any desire to anymore because it's better and less hassle to play any other role. I am not just complaining about support and then leaving I have some suggestions for Riot and how they can make Support more of a desired role to play for all. First make assists more useful in game for supports. this will let supports build better items and give them more reason to assist. Second make playing a support more rewarding than playing adc and other roles. if it is an RP boost of 5% or something else to give a desire to support. Third Have the kills and assists split so that you can see how many assists some one has had over their career in league. This gives value and glamorizes being a support and getting assists. Fourth If you end a game and have more assists than kills within reason like 5/10 give a bonus or reward to the support for doing a good job. Riot I know you have a hard time listening to your community and you don't like to be told what to do but get use to it and start making the least played, least liked, least filled role more play able. This will solve so many problems in game and in the community.
