eu.battle.net/wow/en/character/draenor/Malcador/advanced - I main tank for a 6/7 normal 10m team.
I'll be the first to admit that number crunching and simcraft aren't my strong points, and Rawr goes straight over my head in terms of complexity.
My issue is simply this: Have I delved too deep into the mastery stacking philosophy? I've just hit the block cap with the addition of the T12 legs (and with a little help from Lavascale Minestrone) but have had to gem almost exclusively for mastery and use two mastery trinkets (though I also have Scales of Life available). The main drawback from this is my health pool is...tiny. Be it through other tanks' ignorance towards mastery or just the general view that more stamina is best, I feel as though I might have made a bad choice.
Can stacking mastery to the block cap at the expense of everything else affect my survivability? My threat is fine, but my health pool is a worry, particularly for unavoidable magic damage etc.

Sorry for what may be a slightly haphazard post, I'm still half asleep. Any advice on the topic would be welcome though.
