From what ive seen (and training dummy testing on ptr vs live server).
In my 1850 block value (39% block) block set, ShoR does a little more damage in beta.
In my 1160 block value (12.5% block) EH/Avoidance set, its significantly lower, down ~15-20%.
So it really depends on your gear, the more Block value you stack, the greater the chance that the -30% ShoR is countered by the +50% block buff. Im not good enough at theorycrafting to workout the cutover point
If you have a high EV/Avoidance set dont worry about the loss of dps/tp. This is nicely countered by the buff to SoV.
In my EH set a 5 stack of SoV ticks for 500 exactly every 3 seconds (on both live and PTR).
The ptr SoV has the dmg bonus of approx 300-400 extra holy damage every weapon swing (1.6sec)
This extra dmg can crit, but the crit rating seems unusually low, 1 out of 240 hits i saw from my testing. odd.
I thought it would depend on weapon crit.
(data calculated via recount)
P.S. Im really NOT likeing the exorcism nerf. Yes yes, i know our Single target taunt gets a buff, but I really miss that extra instant 'taunt'
