numbers still seem the same for me

I am finding sustain to be weirdly inconsistent.

For instance yesterday I ran Scriveners HM on my warden healer main with 3/4 of my dungeon tri group and another strong dps, and all of us were constantly hitting the bottom of our resource pools. I have run this toon for several years in every content in the game and simply never have sustain problems. The tank is the same— he was on his DK main on which he can sustain effectively forever without issues. All four of us have cleared this content, but we gave up on Ozezan and turned off hardmode because we couldn’t get the job done.

I logged out, had dinner, logged the same toon in, literally changed nothing, went into a vDSR training run with the same tank, also on the same toon (though he had different skills and sets) and we had no sustain issues. Everything about sustain seemed normal. Got three people their first clears.

I asked after the SH run in a trials discord if anyone else was having the issue, one person said yes and three said no. Came back after the vDSR to report the surprisingly normal sustain, and two of the folks who had reported no issues initially had trouble in runs yesterday evening, whereas the one person who had issues in content the night before had none in their evening run last night.

I notice this sometimes too. I wonder if maybe passives are falling off sometimes? Iirc, there have been some bugs in the past where certain passives aren't being applied in some circumstances. The UI doesn't indicate that this is happening (stats all look the same), but something definitely isn't right with regen sometimes.
