Does Hex actually allow shadow hunter to avoid other skills such as Bash, Lightning, Critical Grenade, or Locust Swarm? I've never noticed it, and I can't remember ever evading things like Locust Swarm. I always get dinged and then heal up. From my play experience, the only useful thing for Hex is to counter molecules, and with the 33% dodge chance on top of Hex only having a 50% proc rate, I've emptied large clips into molecules and not killed them. I've noticed it doesn't apply to wards hitting them either while bubbled (though I think it used to). I'd also really like to test shadow hunter v shadow hunter and see if you can shoot through their ultimate sans lace, as I can not remember ever having this happen either.
By the way, if anyone is interested, a shadow hunter has a .385% chance to hit a molecule inside his bubble. This is not high at all IMO, even though I'm fairly sure it is supposed to hard counter molecule. Especially if Hex is not working against other abilities.
