I don’t think this is true because divine toll with wings+badge trinket+ good rng ( much more likely with seraphim up) can 1 shot someone. So you’re looking at:
Blade of justice for 2 HP
Judge/Crusader for 1 HP
Use seraphim
Press a wings+trinket+divine toll macro to erase someone up to 30 yards away.
This would leave about 1.5 seconds for someone to use a defensive once they see seraphim if they can correctly guess who will receive the damage and if the Ret decides to immediately use it. They actually have the entire window of seraphim to use it if just going for the 1 shot.
