3)Were there any changes made to the camping/resting system?
Oh! Just recalled one more thing about this.
At one point after a battle, a message popped up saying something to the effect of "your replenishable resources are getting low, you may want to rest". I'm not sure if this is part of the tutorial system - the window looked like the tutorial ones - but it did make it look as though there may have been changes to help new players decide when to rest and, by implication, assure them that it's okay to do so.
