Anet really needs to do a pass on this ability. As it stands, it's worse than Mirage Thrust and miles worse than Illusionary Leap.
Damage is good, hitbox is pathetic and rarely connects. Any elevation at all negates the damage portion.
Return teleport is distance locked, beyond a certain point you will just teleport backwards at 600 range instead of "return to your starting point".
No buffer on re-activation. This is fine, but you are locked in the dash animation and remain stationary.
Please look into and address these issues, thank you.
