As I have made my slow comeback to League, I've also noticed that as the atmosphere in the in-game community seems to be getting better, there is still alot of players who behave and communicate well and positively during the game.
_**Just to throw it all away by pointless Report Calling at the last stages of the game.**_
I believe that this is solely because they are uninformed of the fact that their report calling serves no actual purpose.
So my suggestion would be that _Riot should make an informative video/announcement/banner whatever it is that would grasp players attention and educate them about the unnecessity of report calling._
That is pretty much it. I'd like to find out what the boards community thinks about this idea.
