Cloaks can look pretty cool if done right, the AC games are testament to that. They had cloaks in the witcher 2 but they were kinda crappy, it made geralt look like a court jester imo. If they made it so you could wear a full cloak over your armour (Im talking down to the ground length) that would be superb. Maybe if it even boosted your stats a little.. for example, resistance against slashing + bludgeoning by 25%. (or something like that). Im sure the devs could find a way to implement a cloak, the player doesnt have to necessarily wear one mind you .. but if they did they would look like a bad ass & have extra stats to boot !! eh ?
