Name in the title - what specs are you aiming to use at 80/are you actually using because you have had the time to get to 80? Comment and help others by giving them suggestions to improve the spec.

I have two specs set up at the moment, for my Lock (17/54/0) and my DK(51/0/20), both are for PvE DPS/Soloing
