3.22.1 Vixen's Entrapment + Doom Blast still bugged for Ranger and/or Pathfinder

This is not a bug and is not new.

Different character models have their own entirely separate animations. The Ranger's AoE spell animations happen to generally have the contact point (the point during the cast time when a spell "goes off") later in the animation compared to the Witch (roughly 56% through the animation compared to 34%).

This makes very little difference in general, but in cases of very specific timing such as this, the difference will matter - the Ranger would need more cast speed for their cast curse to be applied before the cascade from the triggered one, compared to a Witch.
