I am in a linkshell of 128 casual players we are not elite or hardcore in anyway. So I don't do pick up groups but when our members try to beat garuda we try like hell. We're having trouble surviving Aerial Blast. Plumes aren't an issue for us we can knock them out fairly quick by running into the middle and firing off our AoEs but we just cant do enough damage fast enough to keep her from using her AoE move that damages all pillars.
