@The_Laughing_Man: Yeah I don't understand that at all. I also don't get why people get so angry when someone steals "their" kill. You get more gold if you get the kill, but what does it matter if your team is winning. As long as someone on your team is getting powered up then I don't see the big deal. LoL does not keep track of your KDR and you don't get anymore IP if you get lots of kills. Another thing that bothers me is when the game is clearly lost and people won't surrender. The games are long and it's quicker to surrender and get in a new game than drag out a 50 minute loss.
Cause some people get so bad( its happened to me) they hide in the grass and wait till you did the work and then do a big attack to steal the kill. Then do this maybe 10 times a match.
I think the problem is the game is super dependent on team work. If one teammate does stupid things (feed the other team) then it can cost everyone the game. If one person plays terrible than it can make you have a bad game as well. Not to mention the games are long and if you lose you don't get very much (particularly in LoL) so I think people get pissed easily. That's not to say that they should though, I do agree a lot of people say some terrible things in LoL.
This also happens in the super easy bot matches. People flip out over little stuff.
