Best 4 person all caster/priest group

This needs to be settled with an actual demonstration where DSM tries to keep up with Mage DPS for a couple hours straight. It will quickly become apparent that he is wildly overestimating his ability to sustain respectable DPS for more than a few minutes at a time, despite what his "math" says.

Example of DSM math:

DSM: Did you know that Usain Bolt can run 100 meters in approximately ten seconds?
Non-autist: Cool.
DSM: By my calculations that means Usain Bolt can run from New York to Los Angeles in just 5.2 days.
Non-autist: No man, that's not how that works.
DSM: Clearly you just don't understand math.
