I can't really pinpoint why I'm I felt nothing after I saw all the abilities this champion had. Maybe it's because it's a 'two person' champion but it FEELS like you could have just stuck all this on an Ashe clone and called it a day.
The kit doesn't feel like it takes advantage of the wolf being there. If Lamb marks champions, Lamb could've marked jungle monsters too. Wolf's Frenzy only uses wolf like a mini Malz minion and could have been explained with some kind of other magic, dance of arrows is... Dance of arrows. And Lambs E could have been explained by something else, like a stronger arrow, or using those runes. The ult doesn't even attempt to put Wolf in there.
I'm sure someone could say that Wolf is being taken advantage of, but I don't feel it at all. Lulu gets just as much, if not more, interaction out of Pix to me (her Q actually has a different method of aiming depending on where pix is, Pix moves with her E, pix fires things with his passive and if she moves him to another champion Pix shoots with them I believe). Wolf bites a guy and makes Q have a smaller cooldown while he's biting... Woo.
