Please Make Warwick W create some sort of global howl sound.
Warwicks new theme in the his lore seems very similar to Batman in terms of superstition, such as criminal's (and probably law abiding(?) citizens) being afraid at the mention of his name. So if they hear a howl and/or see the green light, like in the teaser video, they get terrified, especially if they are up to no good.
In terms of game mechanics, since hunting a target gives warwick some serious stat boots and has a huge impact on his ganking potential it would really neat to have some kind of sound play, similar to something like a sion ult, to tell laners to be very afraid. It doesn't have to be anything huge, think like a sion or kled ult sound, just a howl instead of the other sfx. Something like the howls in his login theme would be beautiful.
