Yeh in LoL if you try and give anyone any small peice of advice they instantly go ape shit and flame you to death. Like in solo q its pointless to try and even speak to people, they just get mad if you say anything. I think in team games it work really well to back over the game and see where it was lost, but most importantly to not get mad about it, just accept that you lost and see how it could have been avoided.
But yeh getting your ego out of the game is a lot easier said than done!
