If Your Team Points Out a Mistake You Made
Recognize you may have made a mistake and don't do it again. I swear, everyone who plays LoL seems to think they never screw up- recognize you can do something wrong that way you don't keep making the same mistake!
Yes, sometimes you may have been in the right and the others may be wrong- but at least think about it. Don't just shrug it off and say "Trolls/Scrubs/Noobs" just because- give the comment proper consideration. And for the love of all that's holy- if they tell you you're doing the same thing wrong over and over again- and whatever you're doing clearly isn't working- then realize you're probably doing something wrong and try to fix it!
