The problem we have is that if a raid is happening, a second is almost certainly out of the question.
I'm going to go ahead and assume that I wasn't on when this happened, as if someone says they're in, then that's it. I'm not the kind of person to drop people intentionally. If I was on, then it was a miscommunication plain and simple.
More people are certainly required, we had a push a while back, maybe we need to re-double our efforts and bring more gamers in, preferably with our..... unique sense of humour.
