The best test came on Eck the Ferocious, it was pure single target. Valgard had vigilance on me so I went all out. Squeezed in my Orc racial twice, kept the Ghoul alive the whole time, and got a full minute out of my gargoyle.
I can live with 2770 :) I can't wait until dual specs become available. There are several reports out there of 5k+ dps using a 0/32/39 duel wield spec. That will also allow me to focus my tank spec a little tighter to provide even more mitigation.
I'm still 85 hit shy of the cap in my dps gear since I am sharing quite a few peices with my tank set still. Remember get def capped first, then focus on DPS and you will find plenty of parties to go to.
