Kinetic Rain attack delay when targeting Urns/Barrels?

I'm in vaults of Atziri and when I throw my Kinetic Rain at the urns to break them, there is a MASSIVE delay in the projectiles being created. It doesn't even show the AOE incoming visual for about 4 seconds after I press the attack. It seems to be related to the "enemy targeting" behavior. I wonder if this is also happening in maps where there are breakable objects within my targeting zone?

Bug ref: 727060334

I tested in a map with both monsters and urns. It seems the issue is just on urns/breakable objects. In 1 single attack, half of my projectiles came down on the enemies immediately, and the other half took a few seconds to come down onto the urns. very strange

Bumping thread because issue is still persistent. Now that i'm aware of it, it's pretty noticeable after i throw my wand skill at a pack near some urns and watch half my dps come down 4 seconds late. This is pretty significant
