Shadow build help

Hey guys,

I'm coming back to this game after a long hiatus and my focus as usual will be PvP. I'm currently in the process of building a ci/crit flicker shadow for this purpose but don't really know what the best route is, especially with the recent nerfs to block. As of now I'm just grabbing all of the obvious crit/1h damage/dagger/Es/block nodes that make sense but was hoping someone could help in fine tuning it or possibly get a theorycrafting discussion going if multiple people have insight.

Or if there is a good reference that I'm unaware of please point me there! Also, this is for HLD.

Thanks.

Well since no one is really sparking any kind of discussion I'll start it off.

That's the current build I came up with. Yes I know it's far out in terms of points but just thinking long term. I chose to go all the way to unwavering stance because I have Rage Noose (15-26 physical, 5-71 lightning, 395 accuracy, 38% crit, 70% CM, 21% max ES) and did NOT want to waste my neck slot for stun avoidance (I assumed stun avoidance was still a priority, correct me if I'm wrong).

Any good critiques or suggestions on where to go or anything to change would be good, thanks!

Hear about the flicker nerf?
