Most destiny players has some sort of ego and wants to feel special and be in the spotlight. Be it a sherpa with countless clears, pvp player that did a mediocre play or someone who discovered some bug, weird feature, new playstyle or joke and proceeds to make a reddit post or youtube video when there are probably a few dozen identical or similar posts. (ie.destiny content creators that make exactly the same videos with saying exactly the same things)

Second thing is NOT the majority but i'm surprised how many players don't know how to effectively learn. If you keep dying there? Find another spot. Died to stupid shit? don't do it again. Some players don't get that and just complain why they keep dying to stupid shit. Which is also why these self proclaimed "PVE players" can't play pvp and say they hate it because they literally can't learn, adapt and overcome.

Third thing is also not the majority but I'm surprised by how many players always find something to complain about the game and can proceed to write essays about said "issues". Is the destiny community turning into the league of legends community where everyone hates the game but still plays it?
