Why Everyone Hates You
Hold up, Aragorn. Let me guess: You didn't start this game with a team of players you already know and trust, right? It's just you and five other random players, or "randos," thrown together by the ineffable machinations of fate. In this situation, destiny is not calling for a hero. Destiny (the incorporeal supernatural force, not the game) is calling for discussion. Remember that, like you, these video gamers are playing their games after a long day of school or work, which just means they just stepped out of a slurry of unending and (probably nonsensical) orders from teachers, bosses, or cops. The last thing they want is some weasel-voiced chucklefuck* giving them even more orders during their digital power fantasy escapism.
So instead, try rephrasing your orders as suggestions. "Wanna try flanking them?" will work better than "Flank them now, turbo-nerd!" nine times out of ten. Disclaimer: I have not checked that math, and I do not intend to.
*I'm not calling you, specifically, a weasel-voiced chucklefuck. Just pointing to the fact that every single human being sounds like a weasel-voiced chucklefuck over built-in chat clients. It's called "Sargent's Law of Chucklefuckery," and it can't be helped.
