I feel very silly having a battle happen a square or two away from my camp, and having to walk back to my camp in order to have the ability to select the Heal action. It seems this is strictly an issue with the game interface? An intentional design choice could have been made that healing magic takes time and leaves you vulnerable, but then it wouldn't be accessible in combat. So if Cait can cast healing spells in one combat round, then why can't she cast them between combats when we're not in a town or camp?
