I find it bizarre that you decided to stay in that game when your teammate quit so early on. Most of us just accept our fate and concede if a teammate disconnects, cause 2v3 is usually hopeless. I mean what else did you expect?
I tried my best not to farm the AI in that game but sometimes it's unavoidable, especially late game when the AI goes down in the matter of a few seconds. Of course my teammates weren't exactly accommodating to your request, but then again your attitude and taunting wasn't winning any friends either.
Just concede, it's what the rest of us do, one loss isn't the end of the world.
I would normally concede but your team wasnt exactly the best. We got giants before you and managed to lock your portal 3 times (you locked ours zero times) so we had a good enough chance at winning so that I wouldnt concede. Tbh the A.I wasnt much worst then JewishLumberJack so the game would have resulted in the same way.
Just some tips - lock our portals! You guys could have easily won about 10-20 mins early if you did that.
And its true the A.I often throws itself out you - it is hard not to kill them.
