I can tell you something that might work sometimes. Get better. IDK if you're the problem, but from my experience (i'm a jg main) when laners do things which are too ridiculously bad for me I have trouble taking the game very seriously. For example yesterday I got a mid and adc which were zoned out afk farming. I fought Elise in the river with 0 response..for a very long time, while spamming mid to help. Then Elise caught onto this and invaded. I spammed and spammed and kited her all the way to bot lanes turret and died at their turret...they had no clue. None. Then she literally walked around, right up behind them and killed them. Then this happened mid too. I even 1v1'd the mid laner (I was ganking) and we fought all the way to our turret and she was still out in the middle of the map farming...this whole time. THEN after this happening constantly, enemy jg invading nonstop, then mid joining here (they all realized that my teammates were braindead afk farmers and all started hunting me) I tried to ff at 20 and my teammates agreed that it was "jg diff". Game over. Nothing worse than this. I'm a beast a jg but I have lost games due to skilled enemies...but this....this was not me. This was mid/bot. They don't respond to anything...not even ganks. So if you're one of those people, get more aware and get good. This tilts me so bad, i'm not going to say I int or leave, because I don't want to be banned, but I can no longer play. I literally cannot play. What do you do? You can't attack anyone because enemies respond and teammates don't. I can't farm my camps because the entire enemy team is following me around camp to camp because I have 0 laners. The game is over. I just sort of tip-toe around avoiding everyone, trying to farm what I can, waiting for the damn nexus to go down. I could DEFINITELY see someone inting or leaving at this point. I have HAD people int/leave when it was me and 1 other normal person with 3 of "these people" on our team. They noticed it and either left, or ran it down mid and I did not blame them one bit. No one wants to play a game like this...you can't even play...your skill doesn't matter because you might catch someone thinking they have your back and they just stand there afk farming or w/e and now you die 1v1 (because they fed the enemy jg who ran over a ward every time they ganked, yet still got a kill).
IF you're not one of these people, just say nothing. Trust me. Say literally nothing. Even if you say nice stuff it just tilts them more. If you say mean stuff obviously it gets worse. Don't say anything. Don't ping them either. People spamming pings are just as toxic as inters or people in chat...that shts so annoying. Just do your best and keep quiet. Stop looking at chat and look at your map more (in case your lack of awareness was the cause, js)
