So my group just finished doing crota on hard no problems. But some of the guys gotta go. So on a second run, we invite some randoms on the forums. Worst randoms ever. Not only did they not know how to do it. They refused to listen to our plan. They said it was stupid and that we should just cheese it. Saying they know how to. Btw, the two randoms were together. That said, both of them got the boot.
And this is why I hate doing raids with randoms. What was your worst experience with randoms?
