How do you deal with someone with a bad learning attitude?
So, I had a game where I personally think I did average (A B+ ranking on Taric, I'll need to work on that) in, and we ended up losing. I found myself making mistakes early on in the game such as getting caught out of place, and not catching up to heal my adc on time. However, as the game progressed, I learned from those mistakes and Rumble, Miss Fortune, and I pushed our bot turret all the way to the inhibitor. However, on the other end of that, we had a Mordekaiser who wasn't taking our progress too well.
I had my sneaking doubts that he was a Gold I player last season given that he was borderless in the loading screen, and he made a LOT of mistakes that I personally wouldn't have made in mid lane (such as never warding the bushes and then overpushing while he had low health). The team collectively called him out on it, ranging from simple criticism ("Morde, stop pushing mid, you're going to lose") to harsh criticism ("Morde, you're an idiot, stop pushing mid").
This was pretty much the entire team telling him to stop doing things, but he ignored us and pretty much kept complaining that we were the problem. Throughout the entire game, he ignored our pings, and didn't really participate in teamfights, waited in the bush, and came out only to clean up. At the end of the game, he ended up complaining in the postgame chat about how he was going to be stuck in elo hell forever because of "scrubs like us". Now, I don't play support that often. Support is my second weakest role, but I was last pick, as was every single game I had of ranked so far, so I had no choice but to be support.
But I digress.
To get back on to topic, I ended up learning from my mistakes, and didn't really die too much in the game after the 10 minute mark. My team called him out again in the postgame chat, as did I. In return, a lot of them left, but I tried telling him what he did wrong from my viewpoint. I mainly called him out on his negative attitude throughout the entire game, his lack of warding, his overextending with low health, and his lack of presence in teamfights. Because of this, I ended up getting not only death threats from him (Which, I'm really accustomed to due to Call of Duty back when I was a teenager), but this tidbit from the Mordekaiser. The second picture is pretty much him trying to instigate me into some form of fight (Which, I don't really know why he would do that), including the death threat.
One thing that I tried to do after the macro spam in the postgame chat was asked if he felt better after letting off some steam. Ended up getting another death threat from the Mordekaiser in the end.
Long story short, how do you deal with someone who isn't willing to learn from their mistakes, but rather, blames their teammates, and leaves a very nasty feeling in their teammates' mouths after the fight? I was duoing with my friend and he told me over Skype that he felt even worse than me, and he's not one to really feel in games; he just plays to win, but in this game, he felt like he was back in Call of Duty again.
