I'm traveling from Winterhold college to the Shrine of Azura - it's cold, I don't like (other) wolves and it takes ages. So I assumed the beast form because it can sprint way faster, and stamina regenerates at insane rates.
Is this a wise decision? What are the advantages and disadvantages of using beast form to travel faster? Do I need to kill people I meet to extend bloodlust, or can I kill a rabbit to continue?
Strangely, at the mine a 'fugitive' approached me and then asked me to store something. I was given two dialogue options (! as a werewolf) but could not do anything later.
