This should not be a thing but it's looking like it may. The Q fear combo is a engagement combo the blood sent will see ganks coming well before your wards do. Also warding will be super easy since you have added safety of blood hunt. This is going to be the new Trundle Support isn't it.
Blood Scent is terrible at detecting ganks. The jungler would have to be closer than the enemy ADC and Support, and if that's the case, they'd already be in warding distance.
Lots of champions have some form of hard CC but are unable to perform effectively as a Support; I seriously doubt Warwick would be any different.

Warding is not that risky if you are paying attention to player movement and can infer where they most likely are when they have been out of sight for a while. Blood Hunt may guarantee your safety, but I think you're better off popping it to assist your more capable teammates in their own invades (you have to communicate what you see to your team).
