That story reminds me of a game I had a while ago:
http://www.dotabuff.com/matches/947532218The Warlock on our team is one of my friends and he is super trash at DotA.
Like, he lacks map awareness, has shitty mechanics, doesn't know how to support (or carry or roam or jungle or play any role in general), auto attacks creeps in lane, abandons the lane to farm the jungle at the most random times, etc.
Normally, this guy lanes with one of my friends who likes to play the carry role and is pretty good at it. Good enough that he can still get decent farm despite having the Warlock player fucking up his lane.
Anyway, my friend went offlane Ogre with my other friend on the PotM, leaving the pub Luna to lane with the Warlock.
The first comment that my friends and I made was that this Luna was not going to be happy about having this Warlock in his lane.
The Luna was not happy that he had that Warlock in his lane.
After about 10 minutes of having the Warlock refuse to use skills, auto attack creeps, compete for last hits (the Warlock is terrible at last hitting, by the way), disappearing into the jungle for God knows what reason, and whatever else this guy does in lane, the Luna apologized to me and my two other friends, saying that he couldn't let this Warlock win, and began just A-clicking down a lane whenever he was alive.
Me and two other friends friends just laughed, because we all understood the Luna's pain.
We won anyway.
The Warlock, to this day, thinks that the Luna is shit and that it's not his fault that the lane was going badly for the Luna.
