Brewmaster tanking dodge vs. parry
Parry has higher priority than dodge, but that doesn't change the fact that neither has high priority at all in a monk build that wants to maximise evasion.
Monks are primarily control tanks, which means like DKs they get the most upside from their active abilities. Without looking at logs I couldn't tell you what is going on but just remember that your abilities are served well mitigating spikes, rather than outright preventing overall damage. This is why purifying constantly isn't a good gameplan.
The idea is to understand and predict spikes, and save your various cooldowns for those instances.
Your best stat as an evasion tank will be agility. This is because it gives you so much more than dodge itself does. You get %dodge just by having it, then you get %dodge from the extra crits. Further, you get bigger shields, GotO procs, and all manner of other goodies for it.
After this (and the hit/exp) you should focus on haste and crit. Haste is going to be your chi generation ability. Generating chi has a higher ability to stop damage than a small amount of dodge or parry% and you need to ensure this is not neglected.
Crit, on the other hand, is straight up better than dodge. Rather than flatly increasing your dodge%, it increases the stacks you gain on Elusive Brew, which is a much higher gain of attacks dodged over the course of a fight. The advantage with EB is YOU choose when those extra dodges happen, and that will save your life.
Remember tho that the biggest part of your survivability comes from your awareness of the encounter, and your ability to predict and manage spikes. These are skills, and no amount of dodge or parry on your gear can help you as much as simply learning the ebb and flow of the class, and taking advantage of its tools.
I would recommend regemming since you don't want to be gemming with Dodge/Parry/Mastery.
So regemming and enchanting to those stats will help. Also, level your professions, it helps.
