Oh boy, this is gonna get interesting...
Yes. I'm not sure what the issue with "healspam" was. After all, if your mage is healing, she isn't doing damage or anything else, so you trade that damage or protection off for healing. I'm a bit concerned about the statement about being able to refill every time you go back to camp. Sounds like "fight through two rooms/areas, walk back to camp, walk back to combat area, fight through two rooms, rinse and repeat." At least I hope that isn't how it'll work, but it's hard not to be worried when they've said no heals, limited potions, and you don't heal back up after a fight. I feel like there has to be something they aren't saying that makes this all make more sense, because all I can see otherwise is they "reward" you with fewer trips to camp if you don't take too much damage (or stick to areas you're OPed for?)
