Alt tank trying to get geared to MT Ony/Uld/VoA 10s
I recently joined a higher progressing guild, and am trying to get my tank geared enough for more than just OT in 10s, and at this point, I don't think I'm quite geared enough to even attempt Koralon. While my guild clears Ony, VoA, ToC and Uld 25s weekly, with good progression on hard modes and almost have heroic Beasts down, my tank doesn't get to do much, mainly due to gear. As a result, badges do not come quickly.
I've looked at several threat simulators and spreadsheets, and I get different results from every one, even when I enter all my gear and stats. The guild MTs tell me to be Def capped, then work on Expertise till undodgable, then stack stam, as the dodge/parry/block/etc will generally come from gear. At this point, I'm a bit lost as to what's good and what's not, especially with items like the sword I just got. (Advice on an enchant for it would be nice, can't get a good answer on that, either.)
