Audiovisual feedback for advancing skills

I think there needs to be a different form of feedback for advancing a skill. I think that the visual effect and the sound are a bit over the top and it gets a bit annoying especially when advancing skills in short time. Every time the sound and the glowing appears I somehow think I defeated the enemy and stop attacking but then the enemy is still attacking me

Maybe something a bit more subtle would be good.

 

Also, if you level up many skills at once, the sound clips are added together, resulting in a deafening orchestra hit.
