People always complaining about flaming and such

but I find it more annoying than anything when your team has lost... everything is dead, and your team has been aced. Then your enemies just sit there and stroke themselves while the 1 minion attacks your nexus so they can just farm your grey screen over and over and over. I feel like I want to report this trolling by the enemy team, but I'm just ruining my own 'report credibility' with the system or whatever it is called.
