I know I’m a bit late to the party, but I figured I’d give my 2 cents and rep my guild. We basically touch on all the points that the OP was looking for. We have been around since day one of Classic on Atiesh and we continue to grow. We have 3 raid teams, raiding different days of the week, and all clearing all content. Our Main Raid team clears all raid content in 2 hours. We have enough members that there are always people to play with and we are far from cliquey.
