I believe after reading the dev posts and update notes again, they may of only shortened the respawn in the original areas. So if that's the cases, NMs from zilart and beyond would probably be unaffected
Yea that sounds right. Burned through the first 3 trials for staff WS in almost half an hour each.
PH > NM > PH > NM > PH > PH > NM
However once I got to Gloomantia, it was 1h between pops; Mischevious Micholas is going on 3+ hours since I've seen him. I guess it's better than what it was before, but only marginally. Still need 4x kills on the non-reduced NMs for staff at least.
