They should own the parse on Griklor for sure, but Zerkers are burst DPS as well and they should both be competing for top spot. I raid in two different guilds, on two different servers both guilds have beat TBL and TOV with all achievements - just to give a base line, and each of those guilds field nightly 3 wizards each. Those wizards parse in the middle of the pact - usually around mages (I don't micro analyze every parse). How is the wizard in the group game on an hour long parse with a standard tank cleric 3 dps and maybe a chanter or bard in there? I think the larger issue is, there are no burn events anymore or they are 1 out of 9 raids each expac - Stratos and Griklor being the two for the last expac. Wizards need help for sure, no reason a warrior who is a no DPS class should be beating a wizard at all.
