Rolled a build based on your tree (but not BoR) and so far I'm having fun with it. Currently level 79. The most annoying thing I have to deal with is mana issues. My 4L Wild Strike costs 37 mana and even though I'm only using Hatred, I can still run out, especially on single target. I assume the fix comes in three forms, assuming you don't use BoR.
1) get a 5L or 6L and add blood magic
2) do more physical damage and leech more
3) take Mana Flows or something similar on the tree
...blood magic would also let me use at least one Herald skill. Curious why initially you picked Ice instead of Ash. I have been leveling both but will have to experiment once I don't have mana issues.
Without BoR and a ~250pdps dagger (base crit chance 7.00), my dps has been something like 34k IIRC. Will have to check. Not sure how you managed that much DPS on a lower base damage dagger. Did you take those screen shots with the flask buffs on? I don't use any of that nonsense currently.
I'm currently using Daresso's Defiance because it seemed to work well with this build and I had one...so I figured let me try. So far so good and I might 5L it so I can use Blood Magic. The "free" endurance charges help with this armor for obvious reasons: phys damage reduction, resists, etc.
The use of two unique items also makes it tougher to get your resists higher but I made some gear changes yesterday and things are a little better. For the longest time I was considering using spectral throw specifically for volatile (x)blood nemesis mods because I kept getting one-shot by them, but really once you get the resists up and have ~4k life, it's fine.
My CWDT setup is using immortal call, increased duration and assassin's mark. This helps me get power charges without a PCoC gem.
I started the build using Chaos Golem and now I am using Flame Golem for the damage. Need to try Ice Golem to see if the extra crit will do better damage-wise.
I haven't been using Blood Rage because technically the build can't sustain it. Is it useable? Yeah, if I keep moving and wrecking everything in sight, I will leech the life back. I need to experiment with this more soon since I just picked up the last regen node.
Also worth noting: I have been using Reckoning, Riposte and Vengeance since the character is a melee character with a high block chance. Not really sure how useful these all are but I DO notice that sometimes enemies will essentially freeze when they come near me because one of those was triggered. For a fast-paced build like this though, I would maybe just stick to one or two if you are looking to fill up some gem slots.
Lastly, I am also using two vaal skills: double strike and haste. haste is awesome for obvious reasons. double strike also provides excellent single target damage when you need it and you can store 3 charges of it, so i like it a lot. Just like any skill, you can support Vaal DS with gems to make it more powerful. So for the guys who were asking about single target, here's a buff for you.
