I don't play with Nyx that often, in fact, it's the first time i've played with her since i got her on the last unvaulting, but if anyone is interested, here are my 2 cents on her. I think DE is definetely taking a step in the right direction. First and second abilities seem alright with the rework changes, power with scalability is always nice if not a most in higher levels, that said, i agree with @HuskyTheMilo, Chaos should get a look too, enemies barely do anything except standing there, and because of that, i just use 3, kill the enemies, and move on, while the ability isn't even a third of the way through its duration, so i have to pop it back in for the next "batch" (maybe i'm playing her wrong, but i like to always be moving, which seems to be a key part of this game).
Chaos, here's a few ideas:
1. Each enemy affected by chaos offers enemies or allies in range a damage buff, buff also scales with power strength, (too OP?). 2. Enemies that attack you charge a multiplier that affects the damage of your next ability, but if Chaos is recasted it gets another 10 meters added to its the range (not affected by range mods). 3. Each enemy in range gives you 1 health/s for 5 seconds.
