I am an ADC main and I have mad respect for supports. While I'm still learning and am by no means a phenomenal ADC, a good support means all the difference between me leading the team or going 4/10/2. I think I love the ADC position for that reason itself. Sure, I get to make a bunch of kills late game, but it absolutely requires teamwork, and I like the feeling of having synergy with my support. I don't even mind if they get the kills. It's the most stressful lane and we're (hopefully) working equally.
The only time I get mad at a support is when they abandon me in the laning phase... or if they think they are some brawler tank and tower dive while I'm just trying to waveclear and keep our turret alive. I like to push, sure, but when a support plays more aggressive than the carry, it usually ends up just feeding the enemy carry and RIP bot.
