I am having a hard time deciding what meta I want to toss in my Tempered Titansteel helm come 3.08. I can't seem to decide on either the 32stam 2%armor gem or the 21def 5%block value gem. My current stats are; 24.5k hp, 22.3k armor, 551 def [yeah, I have a def gem i need to change out, and a trinket slot I should change to a stam or threat trinket], 19.5 dodge, 16 parry and 16 block with a block value of 870 [or there abouts]. I have been running heroics for the last couple of days and have not had any real problems, other than some ugly pug experiences. My threat seems fine and I am over the 540 min for uncritability. Due to this I am not sure if I should take the def/bv meta or the stam/armor meta. Any discussion on this would be appreciated, I went through the 3.08 preparedness guide and still can't answer my own question.
At the moment I'm defense capped with a Deep Wounds build and I try to find any and all ways to increase my damage. Just blowing apart threat meters with 8k shield slams makes me giddy so I would go for the Def/5%SBV enchant myself. I currently have 1 or 2 sockets being used by defense gems so maybe I can find the wiggle room to get some more expertise or stamina.
I'd say if survivability is an issue for you, go with the 2% armor one. If you're using defense gems to say above uncrittable, go with the SBV one to make room for stamina and expertise. Excluding Patchwerk and Gluth there aren't many encounters that rely on heavy physical mitigation so the armor is moot most of the time.
Like Cider has been saying, we've become quasi DPS classes that can actually help things like enrage timers. Gearing for more damage is as much your responsibility as it is for a rogue or lock. You just need to DPS the boss while he's facing a different direction.
