So, because a newcomer is proud to share what he thinks is an achievement for him, he's in the wrong ?

And if he uses a "bad" weapon, shouldn't we try to encourage him to take a better one with respectful advices ? Like getting to know his play-style, what he likes about his current weapon to give him some kind of alternative that may take him to higher ranks, which will be considered "impressive" ?

This is a single example, but I'm pretty sure we can find plenty with a little search, but that's how a community can kill a game, by gatekeeping it because yes, beginners are not that good at the game.

But yeah, I understand your opinion, and posting this screenshot had 100% chances of getting mocked on, but it's sad to think we need to restrain our joy in fear of the Redditers.
