The difference between gold and silver is timing group stuns and defensive CDs. Just because DPS is needed before you run out of stuff doesn't make it a DPS race.
what I'm tryin to say is DPS should come second once you've properly handled the mobs with other abilities, such as these bosses in the Brawler's guild, not the main part of your tactic once you juke the K.O. mechanic. (How many of these bosses actually need to be stunned? Every 4th one?)
(Edit: Don't think the noun "beneficiary" can be reflexive like a verb in any way, or whatever the I just did)
