When champions are cloaked by the brush, but are still hit by his E, it makes the same whiff noise as if he just plain missed them. I don't know for sure, but I think this also occurs if they are cloaked.

Hearing the "you have just devoured a unit" noise is essential, since if I missed my slow as they run into the jungle it means they either barely missed or have used an escape. If I hear the whiff, I have to decide whether or not to spend 100 (or more) mana to chase them with Riftwalk. If they were hit and I wasted the cooldown, the mana, or just increased the cost, I am potentially ruining a clutch kill or escape.

So please, for the children, let me hear my normal sound effects if I hit someone through the brush with Force Pulse. <3

That should be doable, and since it is for the children it shall be done. Thanks for the feedback AstorSapolsky, I'd expect the change not in the upcoming patch, but the one after.

Some other abilities seem to have stopped playing sounds when hitting invisible enemies, notably Wild Card, Boomerang Blade, and Lux's Binding. Lux's binding is especially noticeable, as it's impact sound is rather obvious. It does not play when hitting enemies in bush.
