@Thickabe I've found dot builds in general on this server to be tough to make competitive. I didn't even know this enchant was a thing, so I've never tried it out. I don't think tying the enchant to Bloodthirst, Rend and Rupture should be that big of a deal; a melee build can make use of them fairly well.
In my opinion, it's the 20 stacks that drags this enchant down. Yes, having both Rend and Rupture on a target will grant stacks at a fairly fast rate, but how many times will you be able to hit a target with 2x Hemorrhage damage?
