[GAMEPLAY] Warwick Jaws of the Beast Registered Hit Issue

So I've been playing warwick for a long time now and really enjoy the gameplay. I've been hoping that this bug would be fixed by now but it hasn't been so im making a post about it now. Its only noticeable if you've played another champ with a similar mechanic otherwise you might not catch it. If you've ever played vladimir you would know his Q damages and absorbs life from an enemy, however if that enemy dies as you're using the skill it cancels it and refreshes the skill. In warwicks case this doesn't happen tho, the skill Jaws of the beast not only gets used, uses mana goes on cooldown and doesn't give you life either which can be a pain honestly if you're ever against a ranged champion that can poke your health down and you cant get your health back quick enough due to this.
