Assassin/Ninja Help Tstack Melee Damage build?

Looking for a tstack melee damage assassin build for when i get to level 100, no mythics, preferably >20k damage and no negative hp regen (or at least frozen hp as in doesnt go up or down)

if you use pyroclas in the build above, your life steal gets better but you lose 3k dps

 

is 8% stealing going to be enough to offset the negative lifesteal and hp regen? (also my poor ele defences)

 

Negative HPR isn't too much of an issue, but the LS will be painful as hell. Stealing is completely luck-based, so it might be a bit difficult to sustain your health and counter the debuffs

Here's my personal favorite build (37k DPS, 70k EHP, but no lifesteal and roll dependant):
Shawl of Gaea (higher DPS) or Aries (LS for groups of mobs just as Cybel)
Tisaun's Valor
Second Wind (roll dependant)
Nether's Scar (roll dependant
Breezehands (Air Hive)
Flashfire Knuckle (CUR)
Flashfire Gauntlet (CUR)
Recalcitrance (TCC)
Pyroclast [F6E6F6]

 

the -hpr raw is countered by having more than 100 hpr%, so you naturally dont lose hp
tho the life steal hurts if you dont counter it with tomes
8% stealing is enough to use greed for heals, but always carry some hp pots with you

 

It looks really good and I'm probably going to use this! Also it is raid suitable and if not are there any simple changes i can make to make it suitable for raids?

 

It can definitely do TCC as long as you get lucky with the upgrades (Giant and Stonewalker). NoL is a bit harder since the buffs mostly support spellspam, but is still doable as long as you have good team.
