Warwick W Bug

I dont have a video for that, but i trhink its not necessary since it happens every game. If warwick is dead and someone is below 50% HP his w isnt being triggered when he revives until the enemy loses hp again. example: lucian has 30% hp while ww was dead, a few seconds later ww revives while lucian still has like 35% HP but ww's w doesnt trigger, until lucian loses hp again. that doesnt fit with the W's description. Either change the description or fix that 'bug'.
