First Rule of League: It's a Game, Play It!
Disclaimer: I'm incredibly lazy and don't want to open MS Paint to black out summoner names. If the link gets removed, you can find it on my match history.
Notice the time it took for my team to win: some time under the 15 minute mark when a unanimous surrender is possible. Notice the enemy Nasus, still with starting items and about half my level as Yorick.
"What happened?" you ask. Well my lane opponent left lane at level 1 for some unknown reason then came back at level 1 while I was already level 4 or 5. He continues to disappear long enough until Tryn and I push Top lane to Nexus turrets before the ten minute mark. Not long after their team could not compete with that much pressure that early.
Now while I (and no doubt the others) enjoyed the free S rating, this game was disrespectful to those who actually made an attempt to play the game, especially the enemy team. And while I can sympathize with real life circumstances (if there were any), Nasus didn't have the courtesy to disconnect and allow his team to remake.
