Now however, the vast majority of the time, when I use Smoke Screen enemies follow me around, turn in my direction if I circle around them etc.
If I did not use Tactical Advantage I could not even escape melee range!
Also attacks are not always interupted. I had some enemy start a throwing animation before I used Smoke Screen, it still finished and threw a dagger at me (which did hit me since the second of invulnerability was over by the time the dagger came flying).
Not saying the nerf wasn't right, because it was, but all Smoke Screen does right now is 1 second of invulnerability (which is still awesome... but it does cost a lot of disc).
