WHY ARE THERE SO MANY BREWMASTER QUESTIONS ABOUT DOING MORE DPS!! ROAWR
The answer is mostly, no. If you're opening with Xuen and Keg Smash then you're doing all you can. Trinkets will proc at the opening and you'll do what you can. If you want to take a huge risk with your survivability and the cost of nearly meaningless 2s of DPS then you can pull with Taunt, wait till the boss wallops you once to get vengeance, then Jab to proc Trinkets, and Keg Smash with all the vengeance and trinkets procced. This will likely lead to your demise as you'll be putting off Shuffle for a few seconds.
If you have to ask this question then you probably should be worrying about other things besides your initial burst DPS.
I apologize if it seems that my question was merely to increase my DPS.
In fact I asked the question because looking at my logs and doing some comparisons, I found nothing different from other monks.
My fear was to be missing something, so I asked for some tips.
