For instance I know they nerfed Rogues is Assassin / Soulblade still viable?

For instance I know they nerfed Rogues is Assassin / Soulblade still viable?

 

I'm playing one now and it's struggling. Granted, I'm at level three and don't have smoke veil, weapon styles, or biting whip yet, which is where the class supposedly really takes off. Still, it feels like they kind of took a bit of cannon out of what was already a glass cannon build.

 

Again, I'm expecting it to take off around level 4-6. But expect a slow start at lower levels where even a 18/18/14 MIG/PER/DEX assassin isn't generating enough focus to make soul annihilation stand out. Maybe it has something to do with the way I'm playing it - I'm still not sure whether one-handed or dual wield is the better route.
