Maybe dont take it so serius? At the end it's just a Video Game

If you don't want to play it seriously, then don't play. I absolutely hate this mindset. It just ruins the experience for everyone else that is trying to take it seriously. Just because it's a video game doesn't mean that it can't be taken seriously. That's the whole point of the game. What's the point of playing HLL and not taking it seriously? If I wanted that, I'd play Battlefield. The two games (HLL and Battlefield) have become much closer in terms of player communications lately, and that's just going to harm the game.

It's fine if someone is playing and looking to learn, but the answer is definitely not to tell someone to not take it so seriously because others don't care about the quality of the game.
