Hah... speaking of solo lanes, let me tell you what happened earlier today.
We were in draft pick. 4 man with a random. The random's first words are, of course, "me mid". Of course, we don't give him this (anyone who gives a random a high priority lane is asking for trouble). It seems unfair, but everyone knows the probability of good players to bad players in solo queue. Anyway, all the lanes are picked and only support is left. So now, the solo queuer who doesn't want to play support pulls out some bullshit out of his ass:
"Pizza is here gtg"
We don't call his bluff, since if he's going to be an idiot and random afk, we can always just report him and move on to the next game. So true enough, he gets a hard random Nunu with flash ignite. And is still afk.
But my team tries to make the best of this. In the loading screen we decide the laning strategy to account for 4v5. Swain goes top 1v1. I switch with Caitlyn so I fight 1v2 as Vlad bot and Caitlyn goes mid. We do this and other than the early game juking hell I experience at the Vayne + Blitzcrank lane (because of all the ARAM games I've played, I have a 6th sense for juking Blitzcrank), it goes fine.
Then Nunu comes back. He goes to mid. Completely pisses off our Caitlyn player by stealing her farm and intentionally feeding the enemy Kennen. Sigh... randoms right?
Well, after I reached level 6 I was having a ball of a time at bot lane against dumb and dumber. And Swain at top was completely roflstomping Trundle (as is to be expected). Only mid lane was failing. After Caitlyn raged for 5 minutes or so, Nunu finally got the message and started roaming around instead (and stealing our jungler's farm). So he would occasionally come bot and do the most ridiculous things. Like he would be at 1/2 hp and towerdive Vayne + Blitzcrank at their tower. Under normal circumstances I'd have just sighed and waited for 20 minutes, but since I had 1v2, I was so much stronger than dumb and dumber that even though they'd rape that ridiculous Nunu (he wasn't worth any gold anyway), I would just trololol in and doublekill them.
So the whole game goes like this. Nunu getting himself killed intentionally, and the rest of us killing off their entire team because of it and getting ridiculously fed. By the time Swain and I completed our double Will of the Ancients, we could have 2v5'ed their entire team.
The best part? At 20 minutes the enemy team surrendered and flamed everything.
I have never before won a game where a random was intentionally feeding the enemy.
