I have the current health status update frequency set to "instant", and I noticed that health changes from fall damage, void shift, exhilaration, and lay on hands are all delayed significantly. Some are delayed so long that I only notice my health went from full to nothing (with void shift) after enemies in arena already swapped to me 2 seconds after the void shift, at which point I have no time to react to suddenly being at 25% HP.

I tried setting the update frequency to "normal" for a few weeks to see if that fixed it, and that made all the updates a bit slower, and still didn't fix the updates from fall damage, void shift, exhilaration, and lay on hands in particular, so I switched back to "instant" today.

This affects fast-paced arena gameplay, since what I do depends a lot on my current health level at any given time. The fall damage one is not as important, but not seeing an update after void shift, exhilaration, and lay on hands until the target gets hit again is a real problem in arena.

This is in TWW with Grid2 version 2.9.1. This has been happening for a long time, since at least 2024 when I came back to mainline WoW after having quit during Legion.
