Our server first Ossirian kill in AQ20. We messed up on the last crystal, and he started wiping the raid while at sub-1% health. I felt the urge to reincarnate, casted a lightning bolt and an Earth Shock, and he died mere steps away from me. I just can't forget that
My ever first world pvp raid from stormwind to barren during open beta in Nov. 2004, when most people including me at the time being very exciting didn't really know what was coming. That was still one of the most nostalgic moments to me after 9 years.
