Nobody wants to play support because they feel like they have ZERO impact on the outcome of the game

I've been a support main since the end of season 3 when I got to 30 with a friend of mine so we could play bot lane together. I was gold 1 at the end of this preseason and my friend was plat having played hundreds more ranked games than me. So why is it that he played so many more ranked games than me? Because he as an ADC main could play games without me, but I, as a support can't stand playing games without a duo. I feel like the game might as well be decided at the start by a coin toss because no matter how well (or poorly) I do, the mid is 0-6 at 10 minutes or the top is down 75 cs and took ignite while theirs is tp diving bot on CD or the jungler is AFK (literally our farming) or the ADC can't stop getting hooked and doesn't know how to cs under tower, it's infuriating, and unlike another role where I could try to get strong and have a big influence to turn things around, as support, "you can lead a horse to water but you can't force it to drink" is the best way to describe what it feels like trying to affect the game. I'm not saying I always play great (that's really not true) but for every game I play poorly there are 15 others that I had no control over. I can ward, but not alone, especially if they have taken our towers, and I can't force mid to look at their mini-map to see the gank coming, and I can't wave clear and take towers while my team is chasing Udyr through the jungle, or pick someone off by my self. If I happen to come across ANYONE in the jungle while warding I have to run away, and for what? you don't do any damage and even if you play a mage support you don't do enough to change anything if your team is not prepared to act and in the end it feels like they would win or lose regardless of your actions. That is how I feel, now, this season more than ever and it sucks. End
