It's cos nobody wants to pug with somebody who doesn't know the fights. I was in a Naxx10 last week fighting Grobbulus, when some tard kept dropping his mutating injection right in the middle of the room / raid.

Asking for achieve isn't a failsafe way to weed out the super clueless people, but it's one of the easiest. How else do you as a PUG leader know whether the person you're inviting is sh*t or not?

Easiest way is to bullsh*t, just pst the guy your stats and then say dw I know the fights, I got achieve on my main if you want me to switch.

It's cos half the pug guys got their achieve by concidentally being carried by a half-guild run or a bunch of other pug's who overgear the instance. So once you join a pug with a larger proportion of these clueless guys, the pug is then destined to fail.

How else do you explain people who f*ck up the ---- ++++ polarity?
How else do you explain people who put mutating injection in the middle of the room?
How else do you explain the DK in my VOA last night who tanked Emalon right in the middle of the room so the DPS had nowhere to run during nova?
