My Holy Brethren,
I don't know about you guys, but I got really excited about seeing, Invocation of the Dawn (don't let the heroic tag fool you, that is normal version with a 522 ilvl). I did some number crunching and I just don't see it outweighing 1h + shield, sadly. It would be really close but with the sockets on both the shield and 1h, it just sets them over the mace.
As it currently stands, Jerthud, Graceful hand of the Savior + Shield of Twinned Despair, will be BiS.

If it wasnt for the sockets on the shield and wep, I think this mace had a good run at being BiS. Even now, it wont be a bad choice. With all the spirit available on gear, I am wondering how bad we would miss that 938 spirit. We could always reforge the crit to spirit if needed. I'll probably pick it up just for how awesome it is and test the numbers. I don't know, it could be a toss up.
But sigh, Would make some badass transmog possibilities!
Ps: If my numbers are off or anything, feel free to correct me. Thanks!
