I don't understand. Is try hard a bad term? When you say "try hard", I understand it as "someone who puts more effort into the game than me".
You can't expect people to get bad at the game, you have to get better.
I mean, I am a try hard. I sometimes play 15 matches in a row against someone who destroy me and rematch until I beat him. That's being try hard and I don't feel like it's bad.
If you just wanna play casual, and not learn any techniques or improve, then you really don't have the right to complain.
