When you said "rewarding" I think you meant satisfying.
Your right it does suck, here is the appropriate video...

Heres the thing. Here is why I support. I want to win. There are a lot of people with the skills to play their lane/role well. What is often the problem is people who cant support well. If you dont have someone who can do the support role well, or thinks theyre going to rewrite the META by taking kills and CS then those people will languish in lower elos where that may work.
A good support, like one who can set up a good Braum ult, and cover the ADC while they breakout their channel ult isnt something everyone can do. Many people fail to understand their supports contribution.
Its just like the people who try to argue with the support and call them 0/6 when theyre the support.. conveniently leaving off the 0/6/12 part. Cause if the support had kills, they would be bitching about that...
Some people still do recognize the support contribution though. Theyve played support, or main ADC long enough to know when their support is good, and when theyre just "around." Some cant, but some do.

Its hard to see but they say "gj sup" in the chat. Someone noticed the support contribution, and thanked them. While some notice the good, it seem support only really gets attention if theyre dying a bit more than average, then you get a lot of attention.
So thats the support fate atm. If your doing bad, youre shit and everything is your fault, if you doing great... GOOD JOB ADC WAY TO BE AMAZING!!!! :D HERE IS A FREE SKIN!
I agree it can be very unsatisfying to be in support position. Cant be helped though. Iv finished games as a mid laner where I went 3/15/19, and getting all kinds of shit from my team. Then at the end, all that shit talk goes away the second they check the damage chart and see that I have 35,000 more damage than anyone else... yeah, I carried every teamfight and if I had gotten peel, Id have all the kills instead of them picking up a broom and cleaning up after me. Instead I get flamed for dying and called a feeder. People dont see the macro game very often, they only see a tiny sliver and think they know it all. This example of my mid game where I 100-30% the entire enemy team, then get jumped on and the team just somehow dosnt notice this contribution is very common.
So sorry your not getting that pat on the back man. I know how it is. Im right there with you as a support main. Sucks, but a good support helps win games. Do it cause you want to win. Be the teams glue.
Dont really have an appropriate video....
Umm... Ah, here is a highlights video of me and a buddy playing some Overwatch where he does some great healing but doesnt get credit for it... but instead gets credit for offensive assist!
