Hi Barahir,
I’m a little confused.
Regarding your reforged blade, does it already have a DMG% roll on it? It doesn’t seem like it, since you’re talking about rolling LoH to DMG%. Without a DMG% roll, I believe the highest possible damage the weapon could have would be 3996.3. I’m not sure where you’re getting 4.0 - 4.1k from.
If it doesn’t have a DMG% roll yet, then rolling LoH to 10% DMG would give you 3960, which is not terrible. But, since you can reroll the base damage to get close to 3996.3, you might as well just do that and keep the LoH. Rolling to 3996 dmg will give you a weapon with 6.4% less damage than your original one. The extra 4% EQ on the new weapon will give you back 1.29% of that damage.
The 23% AD is a good thing to have, and will take you from 86% AD to 109%, which will make up for the remainder of that lost damage whenever you are fighting 3 or more enemies within a 10 yard radius.
Hopefully, I don’t need to tell you that you should more or less always be fighting 3 or more enemies packed together when using this build. Beyond 3 enemies, the new blade will deal more damage than the old one.
LoH will proc from hard-cast EQs, and it will proc from Leap. It is discounted by the very low proc rate of EQ, and so will not give you very good results. Still, it’s better than nothing.
So, my advice is (if I’ve understood the situation correctly) to reroll your damage range to try to get close to 3996, and use the new blade. You will be losing some VIT as a result, but it appears you are using Esoteric and BoM and APDs, and you also have a decent amount of paragon, so you should be fine. If you feel like you need further healing, drop BR: Bloodshed for BR: STP, at which point you’ll be nearly unkillable.
Ultimately, there are better weapons out there, but this one is not bad. Good rolls on DMG%, STR , AD, EQ%, and your base damage roll (also +max fury) are what you’re ultimately looking for.
