I get really pissed when someone in the raid playing the same class as me and close to same gear as me, just does more dps than me. I'm not a noob, I consider myself as top 3 dps in any raid and if I can't be in the top I consider myself as a failure on that particular class. But sometimes some people on the same setup as me just do sensibly more dps and I get pissed as I don't understand how.
