Stalker's Epic attacks cannot critical
Just making sure you're talking about Shuriken and not Exploding Shuriken. Regular Shurikens should auto-crit from Hide, but the exploding ones are AoE attacks, and as such, do not auto-crit by design.
I'm pretty sure I was getting critical hits using Laser Eye Beams the other day, but that's on my secondary build which I rarely use. (As you mentioned, the Patron single-target attacks do definitely crit with no problems.)

Sorry, I was using Shuriken, the ST one. I haven't taken Exploding Shuriken because I am about to respec out all epic powers due to not being able to critical.
Following the critical formula, Exploding Shuiken should have 50% critical chance from Hidden just like Balls of Lightning which my other Stalker has.
I haven't tested with Eye Beam. Can you confirm?
I've tested it by being in Hidden and after Placate. Both result in no critical damage.
What's left is to normalize all Assassin Strikes and improve Stalker's old sets (Claw, MA and EM)! You don't need to bring back the missing PbAoE attack. You just need to make the existing ones better! For example, make Slice a WIDER and LONGER cone.
I've posted this twice in the Stalker forum but I figure that's the wrong place to post since that's not a Bug forum and the dev seldom goes there.
I just tested it last night with my throwing star from Weapon mastery. Nope. They still cannot critical.
Stalker's patron attacks can critical so I would assume Epic powers should critical as well. Please fix.
