So when the sources of damage add up to around 200,000 damage that you could take in a single second, are you really suggesting that we just leave quarter of that up because we don't have the resources to purify it? We could've got a bit more haste, thus more chi to get rid of it, but nah, let's instead get more mastery to push EVEN MORE into that DoT. Mastery which, currently, doesn't really provide much per rating point anyway.
The vast majority of our Stagger comes from the baseline amount (20%), and Shuffle (20%), 40% total. From there we get a baseline 4% mastery (4% extra stagger), then every 1,200 rating increases that by 1%.
With my current gear, I could switch everything over to Mastery and get an extra... Roughly 6,000 mastery. An extra 5% stagger. That would take me to about 50% of damage staggered, at the cost of a ton of haste, hit, expertise, and crit.
It just doesn't add up. There's nothing to suggest that stacking extra mastery would be more beneficial in the slightest. We already get so much from our simple baseline abilities, and when mastery scales so badly why on earth would we want more of it?
