Your ignorance is the Devil's bliss. Every time you scorn what confounds you, he smiles. Every time you sow the fear of him where there was none, he laughs. It's you he loves. It's you he thanks in his evening prayers. -Everville
in our guild it is a monk and berzerker sharing the number one spot and very rarely a rogue pushing them to 2nd and 3rd.
In my guild it's wiz/monk/ranger with a rogue thrown in there every now and then. Seems though in our Dec AA we'll be getting a lot towards sustained with HHE and shorter disc timer on assassins. But the way we are looking at the start of the expansion compared to casting classes is pretty good. We are usually far behind at this point.
