Imperius' Volarous Pursuit, why doesnt it work 90% of the time?

So everytime i “use” it it either doesn’t teleport me to an enemy or its randomly greyed out. Sometimes its not greyed out and when i press it it still doesn’t teleport me even if i’m literally hugging an enemy.
Sometimes it works and i think “Okay it works now but im in the same position as it i was last time so why now and not last time?”.

This is so confusing, why doesnt it work at times? Why is it not greyed out but yet unusable? Why is it freaking melee range?

Visual evidence of your claim would be appreciated

If a bug this belongs here though
