Gloomerang's abusive exploit

Gloomerang is clearly intended to just have 4 charges, slow attack speed, and a CD. However, if you "animation cancel" it by constantly swapping 2 gloomerangs, you can double the charges and have virtually infinite attacks, while also attacking faster due to the animation cancel.

This outdps most melee rift weapons, also howlitzer, and also Walter's slingshot. Since gloomerang is ranged, this "animation cancel" is easy to do. Which feels unfair specially considering Walter just had his skill tree.
