Not by me personally but then again I was never that happy with how Protean was addressed in Bloodlines. In Redemption you could change into a wolf, sink into the earth to rest, and turn into mist which was awesome. Protean in Bloodlines is extremely linear so I ususally steer clear of the Gangrel Clan.
Though I must admit the new Animalism is freakin fun as hell to play (not trying to brag), so I find myself creating a Gangrel or Nossie just for Animalism.
