Wandering spirits overnerf

Since the hidden nerf to channeled wandering spirits , they became really weird to play.
Since you stand still to channel you are extrely vurnerable.
The Reason i got why the spirits dissapear after channeling is , that there are niche exploit cases where you just spam the spell but why : 1.Let the reveal duration buff ramp over a period oif time like 1-6 seconds so you need to channel to actually benefit from the note 2. Increase the cooldown of the channeled version .
But letting all Spirits dissapear is just really weird and clunky. I hope someday that skill gets looked at again , even if it a non-meta skill.
