Lol damn, i wonder if the lag is better with 2.4.1. I tried blessed hammer in group, the damage is decent but when you have a screen full of monsters it's unplayable even after they changed the damage numbers to K and M.
I don't know if it's still the case on live but the Heaven's fury proc from the Ivory Tower used to heal you up if you had life per wrath spent although the proc does not use up wrath at all. That was one of the OP things about the HF build last patch. As Bagstone mentioned, it caused insane amounts of lag (at least on EU...) so it wasn't really playable but the damage was crazy. I'm pretty sure they fixed the lag and damage parts but ivory tower might still be bugged (unless that's intentional...), anyway.
