[GAMEPLAY] "Cannot cast that spell right now" is MUCH louder than before, and gives me a headache.

I play spammy champions (like Evelynn). "Cannot cast that spell right now" has had its volume increased this patch. It is giving me a headache (and this might be the source of many other people's strange headaches - it might not actually be the new HUD text causing it).

It is especially noticeable when spamming multiple skills on cooldown in a teamfight (you literally can't hear anything else).

If this new volume is going to stay.... Can it have its own slider, so I can decrease (or mute) it without decreasing my other sound effects?

EDIT: If this thing doesn't get its own volume slider, I'm literally going to have to modify my client and delete this sound from my game every patch. It's that bad. I can't even play the game like this.
