Bronze Player (me) being flamed by a Silver 5 adc main
I am currently in Bronze 2 (yea I know, the worst in the league), and I have been flamed by a silver 5 (kda of 1.12 and kp of 34%, an adc main).
This silver 5 adc main, threatens that I will be banned (for whatever reason that I don't know, possibly siding with a Yi who was "feeding" and being flamed by an Ahri, who flames her back, this adc also reported yi for verbal abuse (which he did) and intentional feeding (which is definitely not true)). My reaction was, what did I do wrong, it is you that did something wrong.
This is what this adc did: flames me for "kill stealing" when it's actually "kill securing." There was one instance where I killed a veigar using flay (I was thresh while this adc was MF) and it wasn't intentional, and she was very low on health and a Varus was coming. She proceeded to farm with low health and died from the varus, even tho I pinged retreat multiple times. And also I "kill secured" 2 kills before that, but it wasn't intentional either. After she died multiple times, she was like "man, I wouldn't be (f word) if thresh wouldn't steal my kills."
During mid game, she keeps stealing camps from Yi, who was constantly being flamed by both Ahri and MF (who constantly says he will get a ban and that he was trash.) She keeps getting caught out by Veigar's wall despite me saying "be careful with his stun and ult" and me pinging constantly. She can't even use ult properly, and there were instances where we could get a kill or 2 if she was patient enough to use her ult.
TL:DR: She is a very bad adc, she keeps getting caught out (especially when she was farming and when I was pinging), and this adc after the game says, "enjoy life in bronze, trash, unlike me, I win. You don't. I have a kda of 5 as MF." She did have a kda of 7 the game before I played with her (ill just say this adc is a her because he/she played MF), but when I looked down of her match history, she has multiple games with a kda that is less than 1 and some game less than 2.
What I really don't understand, is how there are those players who just don't see themselves as a bad player in the lower league. I made some mistakes too in the game as well and noted myself what I have done wrong and what I should have done. But this MF on the other hand, keeps talking trash about me and saying I will stay in bronze life forever, when she doesn't realize what mistakes she has done. She thinks being silver is better than bronze, but she's silver 5, does that really make a difference? She just got out of bronze, and feels superior about it. Not only that, I don't play league 24/7. I have school and I don't usually play a lot since my parents are very strict about it so I don't usually climb fast enough.
Now I am having a fear of actually getting banned for something I didn't do. My question is: what did I do wrong, and is it all my fault? What can I do next time to avoid this kind of situation? I am just in a mental breakdown after that game, and I don't know what to do if I ever encounter this situation again.
