Kadala just gave me a primal Shield of Fury with the following stats:
+1000 Strength
+11% Block Chance
Gain 1660 Life per Wrath spent
Increases Heaven’s Fury damage by 15%
Which stat should I reroll to crit chance? The block chance or the life per wrath spent? Thanks!
It doesn’t really matter much, since this is a Shield with 2 bad stats.

Of course it matters - given that it is very hard to get the 3 rights stats (critical chance, heaven’s fury damage and cooldown), many of the top players in the ladder settle with 2 stats…
Of course it doesn’t matter, since you want the correct stats on the offhand, no matter if it’s a normal, Ancienct or Primal. And yes, rolling spell-effects on offhands is a PITA.
The most useless answer I ever got… thanks a lot for not helping. Next time if that’s all you’ve got to contribute, please abstain 
Wrath Spent for Critical Hit Chance. Your Primal is better than my POS Primal.
great shield for lazy shotgun thou…
For ivory tower, I’d keep block%, reroll LpWS.
For manually cast Fires of Heaven, I’d keep LpWS, reroll block%.
I recommend that you re-roll Strength into Cooldown (or Crit Hit Chance, although imo cooldown is a safer option). This will give you a pile of healing and a natural shield block chance of 31%, correct? At this point, I would swap your Laws of Valor passive for Divine Fortress, which will give you a perma 31% Armor bonus. A nice, survival-minded design.
Remove the life per wrath. It scales the worst, is largely pointless due to how much damage you are taking the higher you climb (which is a big problem with healing and tanking in general in this game) . The block chance at least can give you some extra potential damage reduction and can count towards other passives.
LPWS to 10% CHC
11% Block Chance good for Lazy Shotgun build.
your shield is still better than my primal
