Indeed but if there isn't a cast bar, you can also generally rely on - if red aoe disappears, it snapshots, as well, and both these things usually align as well if there are both.

That does happen with tank invulns such as Hallowed Ground, but again I've never seen this as some kind of "tick rate" issue but rather that there is a long animation that occurs where your player puts up a shield around them, and once that shield appears around them, the buff gets applied.

Ability effects should just happen instantly and not necessarily be tied to the animation. I know that isn't as lore-friendly but it makes the gameplay more reliable and smoother.
