I know it's got 11sp but at the same time wouldn't the stormhammer's proc make up for it?
I couldn't get the antu'sul mace from ZF with the "mini-thunderfury" proc yet, but I'm at a stage (50-52) where people bitch that I give them Salv and I have a hard time keeping steady threat without Salv without having to drink every pull (As opposed to being able to go 3-5 pulls before a sip with Salv).
paladin tank btw, since at this point of 50+ there's a very real chance gear will last a very long time due to poor itemization or just shit rng with drops
