Pick up groups drive me crazy. Why is there so much fail all the time #wow
There is so much fail, because you're in a group that is randomly selected. Those people that are full of fail are probably pretty cool people that need some instruction. Let me assure you that so many cool people play Wow, but they are intimidated by the party paradigm.
If they come off as so completely devoid of any knowledge of WoW that's one thing; if they have a somewhat basic understanding of the game, make them feel appreciated and help them to learn. It'll make both your days better.
