Don´t be a snowflake, boys, grow your thick skin.

I am a very calm guy, so I generally keep my opinion for me, but as i was reading this subject, i did a relic run in dzemael, and the tank drove me nearly nuts, because it was clear, he only did his Tank for quick invites [0], but was serious enough to buy a full stack of Wootz HQ for his left side...
He failed so much, the healer decided to fake-dc after the first trash after first boss ^^
basically, just be nice to each other, after all, it´s just a game, don´t flush down your mood because of such things ^^
[0] tbh, my first run to 50 PLD was for exact that reason, but I must say, I never encountered any insults, usually leave the duty with 2-3 Commendations, so some guys must have really bad karma, putting together the perfect matching people in the duties ^^
