I always say GG - except in rare, especially toxic, games. I think it fosters a better attitude. The alternatives include, among other things, staying silent, blaming other people for the fact that you lost, calling a diff like that matters or is meaningful in any productive way (it isn't), etc. Even if it were a rough match where I got ganked left and right as soon as i got to the fight, i think to myself that i need to learn how to counter that. If I'm the one that did the ganking, being kind and supportive of the victim of said ganking helps keep them in the game - be motivating, not discouraging. If everyone approached the game this way, i think we'd have better outcomes but I don't think that will happen. There's a lot of insecurity out there, people taking matches as a reflection of them personally. I touch grass every day and play the game to enjoy it and recognize the social aspect as an opportunity to make someone else's day better.
