Devourer

So I've been using Devourer quite a bit since it's release and I have noticed some strange occurrences, specifically before sated. (as kayle)

1. when you die your wolf stays behind and grants vision of the area as you would.
2. at times the wolf leaves you and you lose attack speed until it returns.
3. random champion loss of control when wolf is not present.
4. broken after sated anyone else notice any of these?
