But even when you use the Ring of Hircine you can only shift twice a day.
It's much easier to go on a three city killing spree with out ever shifting back. I went from Windhelm, to Riften, to Whiterun on one change. Didn't fast travel (because you can't when in WW form...), and I just killed and ate anything that moved along the way.
So in an hour I had the WW Perk tree maxed.
Irony: My base character is Khajiit.
