I'm really considering maining ADC, just did a game on ADC because everyone was poop at it apparently, went tristana, even though I haven't played her for like a year, and that was AP Tristana as well. I had an idiot support Thresh, first 5 minutes afk under tower, didn't ward, even when he had a sightstone he just constantly forgot to ward, as in not putting down any wards, not putting them down to scout and also not even putting them down when I told him to put down. I mean he put down 13 wards in a 37 minute game, that's with a early sightstone. This should be at least 30, especially because you normally reposition wards quite often.
To add to that, he kept going in like an idiot, we had a Lucian/Karma lane, and if you follow up with your Q, Karma is gonna W you, and since he wouldn't leave a lantern behind, I had to W to go in, but since he died so quickly, I just continued farming, because it was the only way to not be useless myself lategame.
Still, I didn't suck, I farmed up, properly last hitted (he made me miss a few because he had relic and didn't time last hit properly, I really dislike relic on Thresh, it is good, but because you don't get the damage bonus, it's really annoying to plan, both for adc and sup)
I just had another game with Trist, now I had a blitz that fed 4 kills to vayne (fb, then 2 while they waiting and taking our blue, then intentionally fed 1 in lane because he went full troll, then he trolled other lanes because I told him to duck off), yet I was still able to out farm a vayne/thresh combo 1v2. Obviously she was much stronger, but still.
