I have been staring at this card since i got my PvS and i haven't been able to bring myself to use it until last night. I put together a priest that ran clerics and metatron, with some temples thrown in. Let me tell you that if the effect die is on your side these little ladies are worth the weight in gold! They hand out dazes like candy, and with a little luck, (and maybe malakis basilica) the stun chance on the ranged attack can be a huge swing!
I ran 2 of them, with a handful of DBIs and Asyran clerics (to help heal ehren) and with a gator toughness they can stick around for a while. 2 armor ten life is pretty awesome. I don't know that id make one my holy avenger, but they make a really great little shock troop with an equal daze chance on both attacks. Anyone else have better or worse luck with them?
Either way if you haven't tried them yet givem a shot. You might be surprised
