Bug: Nerien'eth set not proccing from multiple sources of direct damage

HankTwo

Hello, I just wanted to report the following bug: after I had the feeling that Nerien'eth wasn't proccing as often on the backbar on my magplar dd as it should, I did some testing with multiple dummies standing closely together and I could confirm that Nerien'eth is never proccing from:
- the initial, direct damage component of blazing spear
- the final, direct damage explosion of unstable wall of elements
- both the initial small damage and the final explosion of purifying light
- as far as I can tell the burning light passive
- the entire channel of radiant glory. Still, this would be more a question of definition. Are beam channels direct damage or not? Damage shoes up as white numbers instead of orange and the skill is blockeable which both indicate direct damage.

I bet there are a lot of other sources of direct damage out there that will never proc Nerien'eth, but in case of the above its bugged for sure. If this gets fixes the set might become too strong because of the rather high damage and very short cooldown, but these things can easily be adjusted and sets shouldn't be 'balanced' around bugs of course.
