The more I think about it the more I think it is a shitty patch too.
There are classes that do not need complex checks to produce good output.
Mara's Guillotine for example, one of the hardest hitting skills in the game - you see health bar is below half - you hit it, you crit it, you kill it. Job's done, a very skillful play. You do not need NB and can jump on the forums laughing.
Taking example of the opposite situation. Witch hunters attacks from behind. Battle is like a crazy dance party - everybody is moving non-stop and this second I am hitting from behind, next second I am not. And this goes on and on and on. You really need NB here. Otherwise your best damaging attacks are not being used.
These are just examples of two classes but clearly one of them has just became very much different after this shitty patch.
