Just play fucking Janna if you get shoved into Support. It's literally free elo, Janna is so simple. Shield your adc, peel, Jannasec. Oh, the rengar is about to shit on your jinx. Just toss a tornado and continue on with your movement speed advantage. Why do you think there are so many Janna OTPs in Masters, Diamond, and Plat. But they're not very good. Support is easily one of the most important roles. You can be the deciding factor towards winning or losing lane and the game. You're the one warding/preparing to evade that 2:30 Level 3 Cheese gank. You're possibly the team's tank and engage. Support might not be outputting 800 damage tumble crits at two items, but even playing somebody like AMBULANCE is enough to do your team good. Even then, just buy a fucking redemption and carry a teamfight. Personally, idk how support mains do it. The amount of verbal abuse is close to junglers. They have to literally deal with protecting some flaming Tyler1 enthusiast or Gosu Jr, the Bronze Vayne. Rito can't make Support fun because they really aren't meant to be damage carries. Zyra being an exception. Zyra is just a straight lane bully. A good Zyra shouldn't lose lane, or ever have lane pushed. She can't lose trades and despite her lack of direct buffs to the adc she provides CC and control of the lane. Her plants also do so much. I cry when I get put against any ADC vs Zyra support. It turns into a "don't feed" lane. Can't harass, my hard push is countered with her own push, and her plants are downright a pain. Idk, feels bad being a bot lane player in this meta.
I play Thresh and Lulu personally, only because I feel like I can carry harder if my team are monkeys. There's no point to complain about Autofill or having support in your queue set up. Why? Because it gets you games faster. The sacrifice with activating autofill was getting matchmaking speed, at the loss of Game Quality. Yeah, you might get the occasional troll guy that feels obligated to play full AP Lux as your support, but at least Elo below gold aren't waiting 10 minutes or more to find a support. Why go back to the days where you were waiting so long you could literally play skyrim between games? It's not ideal. I would prefer to wait, but as long as my support isn't a troll going LB, who cares? Most people are nice enough to swap if you aren't just crying "I PICKED MID/JG WTF SWAP OR FEED"
Notnimble also has a point. ADCs are so oriented around being carried into the late game, to where having a good support is ideal. Duo queuing and having a support is very good. The amount of communication when comparing a normal lane and a lane with comms are huge. I don't think I've lost lane when I've played Jhin and had one of my friends support in a long ass time. That is, unless we fuck up monumentally hard and die to the Level 3 Lee Sin. Then we come back to lane and there we are, pushed into tower against Level 4 Vayne/Nami while we're Level 2.
