nice to have not that I will use it.
never got the appeal of running around smelling like wet doggy :shrug:
It really depends on how useful the forms are, while it may be fun for a while I cant see running around as a wolf (unless of course you can run faster as a wolf and travel between towns quicker, but then why run when you can turn into a hawk and fly?) being all that useful, a werewolf maybe provided you get bonuses in combat but a wolf? Probably not. Of course that is not to say that other forms would not be useful, as said before you could turn into a hawk and fly or perhaps even a rat to travel through small holes and tight spaces, if you want to take it even further maybe you could take the form of other humanoids and use it as a disguise to get into places you otherwise wouldnt be able to get into?
That being said even if shapeshifting diddnt have a practical use it would still be nice to see in the game if only for character flavor, of course I dont expect Bethesda to add such a system as I would wager that it really isnt very high on their list of priorities (especially if such a thing had no practical use), but still it would be nice to see. I guess if we want to see such a thing we will just have to mod it in ourselves.
