I am currently using STR 4-4-8-8 Wis 4-4-8-8 with my left over point in the first box of sta. I use to have the AGI/Wis Set up pre-EOF then I switched to the STR/WIS set up shortly before EOF came out. While I agree with you the extra 300 mit isn't that big of deal, unlike pre-EoF, I still really like the +19.2% DPS 9or whatever the exact is).
Tanking named mobs post EoF is all about your HP and resis these days. Once your into diminishing returns for mit it doesn't really matter I sit at Ithink 61.2% mit by myself right now and it doesn't move a whole fricking lot when I"m the MT. From what I've seen resis are right up there near the top of the priority ideally you want whatever resis you need vs the mob sitting over 8k+ and HP which has always been a big deal still is.
I don't disagree with the people who have taken the int or agi lines but I as of this moment because of adornments and other gear I am sticking with my current set up
