The need to use other players (bards) to regain vitality is game breaking. When there are no bards around and I'm too tired to continue training my skills (as happens far too often these days) it completely ruins the experience and just causes frustration. Other methods such as sleeping in beds or sitting in chairs should be available. Bards are an interesting and social construct which is great, but they shouldn't be relied upon so heavily that it ruins a players day if they aren't around. Awesome, awesome game otherwise!
