I was reading all tanking guides, and i wanna say big thanks to Vene, Xav, Cider, Satrina and others for their great help. And now to my question.
All guides tells that Expertise is ultimate threat stat, and i was stacking Expertise on gear, and gemmed with exp/sta gems. I had like 48 expertise, 121 hit rating. But block value with this gear is like 900, and i found that i actually do more threat in my block set, with 14 expertise, like 160 hit rating, and like 1500 block value.
Feels like expertise not so good, if you hit for shitty damage, even if not dodged/parried. Am i right, or i did something wrong again?
Can you find a balance between 900 BV/40+ expertise and 1500 BV/16 expertise? I'd aim for around 26, thats where you remove dodge from the table. More is fine because it removes parries, but I think the problem is you are going too far one way or the other. Its important to balance your stats.
I would first ask, where is the level you have noticed the drop in threat and damage, trash mobs or bosses?
For trash mobs 48 expertise is by no means needed, in fact mostly wasted. Another thing is that block value gear on average has higher strength, so that means that across the board damage will increase.
For trash and 5 man and some 10 man content I use my block rating/block value threat gear with a decent amount of expertise (at least 26). For 25 man raids I may use the threat set for trash but use avoidance/expertise gear for bosses. You don't have to lead the dps meters but the expertise on bosses along with more hit rating ( I am for the most part hit capped in my avoidance/expertise gear) it will even out your threat and damage.
