So my main raiding role is as a bear, but on single-tank fights I'm trading paws for claws and doing my best to let it rip... Most of my kitty set is my bear gear with a few pieces I've been fortunate enough to get duplicates to itemize for kitty, but to date no 2nd Tsanga's Helm
My question is which of these helms would be better for my kitty set:
Tsanga's Helm with the tanking glyph, stam/2% armor meta, stam gem, and crit reforged to dodge,
or...
Membrane of C'Thun with the dps glyph, agi/3% crit meta, agi/mastery gem, and expertise reforged to mastery (just picked this up tonight).
(Armory for reference, logged off in my 'kitty' gear)
