Please remove the cast time on dark exchange

Please remove the cast time on dark exchange. Using this ability feels clunky in the rotation due to the cast time it has. with all the other changes to cast time ability's this one should be looked at as well. this ability functions similarly to other class ability's: warden Betty netch and morphs no cast time similar function, Night blade siphoning strikes and morphs no cast time similar function. with all the proposed changes to combat to make it feel smother the ability dark exchange should also not have a cast time as well to make it feel better to use in the rotation.

Plz take a look at this

Thanks
