heh don't feel bad, I remember some time back when I was gonna hold my first guild raid to SWP, got alot of people from outside the guild and went there only to have a tank that died after 2 sec on trash mobs, then the rest of the raid group said noob and left... well in the end we who stayed went to ZA instead only to wait while trying to find a tank but after almost an hour of not finding one we disbanded the group.
Wonder why I never hold raids? Just alot of work and time effort on something that usually screws itself up, it's much easier to let other people make the group and just join em...
Don't get me wrong though, I really like when members try and make guild raids and whatnot but don't count on me creating one...
