PoE Vampirism, Channelling builds

So with the release of the 'monsters deal 25% less damage, 50% more life' I think Assassin benefits more than anyone, especially because Opportunistic grants -20% less dmg taken when 2+ rares around, and 8% less from Infusion results in enemies doing 0.55x the damage. I somehow got 400k sirus DPS with severe restraint in terms of the items I chose not even counting the release wave damage. Scorching. This is obviously a template and not a full build but I'm surprised at how good the numbers look on this. Comments welcome.

Hi, lately i've been playing stormburst inquisitor, to great success, done most content in the game including feared, it's reasonably tanky and worked well on scuffed ssf gear, scaling nicely as i went through the new atlas. as it's my first time making my own build, do you guys see any glaring improvement here or any good opportunity to min-max? i've been getting better at crafting gear as far as ssf goes, so any advice is welcome, thanks :D POB:

Hey guys, I'm asking for some ideas/critique/help with my possible Lighting Tendies starter for 3.17 Some highlights of the build: Defenses: 20k+ armour, Petrified Blood, 2,1k Elemental Aegis, Reflect Immune, 1k ES, 5k+ Health, Corrupted Blood Immunity, Shock Immune, Reduced effect on chill and ignite (50%+) Life Recovery: 400 hp regen, 1k hp leech, 50% damage taken recouped as life, 3% life recovered on kill 1,3m current dps, should be around 3m dps with Phantasmal gem in 3.17.
