This will be particularly useful for people in PvP when you can get Death's Retreat to actually work properly.
But currently Roll for Initiative has a very unique behavior with Deadeye's Kneel.
If you were to use "Roll for Initiative" while kneeling, the skill will treat it as if you were standing and will roll you back. This means that you will immediately have access to Death's Retreat to gain further distance. After a small delay you will be treated as kneeling again.
