Shockwave does not work as intended

Shockwave should be activated on melee hit or at least that is what it says. Meanwhile it activates per attack.
Lets use my example - I use Tribal fury + multistrike. Shockwave activates only on the first hit out of three and on all enemies that was dealt splash damage.
Either change the mechanics or change the wording of the skill.

Yeah shockwave is all scuffed up. It is proccing more than intended in a lot of the cases. Plenty of streams showing that you can stack it insanely.
