There was an earlier post in this thread (2nd or 3rd post) that asked about using Superstition over Tough as Nails.
Personally I've got pretty low AR, it's at about 460 without War Cry so I would imagine Superstition would be the go for me. The pants I use are on my monk in case anyone who checks is wondering why I'm not wearing any. I'm planning on trying swapping Overpower - Crushing Advance for War Cry.
However, when I toggle Tough as nails and Superstition in D3rawr I get an EHP boost for TaN but not for Superstition so I was wondering if any of you guys know why that might be? Is it just too hard to calculate?
Incidentally, the MH weap on my monk is the same one I use for my barb. Easier to swap it over than buy another one. I'm just running with Skorn at the moment coz I got a bit bored.
