Also had a weird experience recently.
I was playing Sejuani. We didn't have an ADC; we had a Zed and a Yasuo. We didn't have a proper support; we had a Maokai.
Come start of the game, Yasuo was AFK. Maokai ran down mid lane and when questioned about it, replied "ff".
I was refused a leash in the jungle, which given Sejuani's terrible clears, made for an agonizing early game experience. What's more, the enemy Nidalee decided to camp me.
And then to top it all off, when Yasuo came back about 15 mins in, he promptly sat in a bush. When asked what he was doing, he proclaimed, "I am ward."
Then something strange happened.
Maokai, you see, actually did go to his lane -- and he played the 1v2 very safely! My entire team also understood that I was very weak early; not only did I have no leash for my first clear, but Nidalee was camping me hard. Rather than trash talk and blame (e.g. "why no gankz jg??"), they worked with me. Top lane (Fiora) and Zed made habit of chasing Nidalee out of my top-side jungle (which I'd warded with a tracker's knife), which netted them a couple kills and allowed me to farm. With that farm, I was able to support the bot lane Maokai, who did a very good job of setting up successful ganks for us both. The enemy ADC, consequently, struggled to apply pressure.
Yasuo, despite his initially trollish behavior, eventually manned up too. He was way too weak to be of any use in teamfights, so he split pushed constantly to give us pressure in other lanes. By the end of the game, he had enough farm to contribute to team fights as well.
Ultimately, despite a rather dire-looking early game, we pulled through and stomped the enemy team handily. If there's a moral to the story, I guess it's this: teamwork is awesome. When you scrap the tilt and work together, even the most dire situations can be turned into victories.
Who'da thunk?
