Don't screw your ADC... please...
So I just had a game with an Annie support. Everyone dies bot lane pretty early, killing each other. We both get red wards, place them in tri and river bushes.
I'm farming, in a bad spot to defend a ward in river, they kill one.
"If you don't respond to me then I'm taking your farm," says Annie.
I come back with, "You didn't even say anything???"
"They're taking our wards and you're just sitting there."
(Not only was I in a bad spot to try and stop them, I was underleveled, as their Lucian had gotten back to lane first.)
She proceeds to start burning spells and everything on farm. I ask her to not screw me over like that, she tries to fight them, I've got nothing to help with, she dies. I let her know that if she takes my farm, I'm not helping if she wants to fight... because I can't. It's pretty simple... an ADC is going to be useless without any farm, and especially if the support leaves lane... which she did. So I mute her as to try and focus on the game and get away from any further aggression from her.
She goes top to support Kayn, fine, whatever. Lucian and Trynd (Trynd supp, lol) stayed bot. They get first turret, I try my best to stay back and grab what little farm I can.
Now, this leads to an interesting situation... not only does my support leave me, but then since I'm underleveled and underfarmed, but the rest of my team starts to get angry with me due to not roaming out of lane more and helping with teamfights... but how am I supposed to when I won't be able to do any damage because I've had restrictions in the laning phase? So, of course, I try to help, and am met with, "you do no damage." Well then let me farm up so I can do damage... but no, people seem to tilt so hard because they can't stay safe and let the ADC catch up. I see this in so many games anymore, not only when I'm playing ADC, but with any other that ends up behind from one way or another.
Just keep in mind that an ADC[arry] can't be that when put behind.
Be respectful, don't tilt teammates, and just focus on teamwork in a team game, guys.
Good luck out there.
