Camp is completely unnecessary. You can just heal yourself easily with a level 1 healing spell. A camp/resting system makes only sense in a Vacinian spell system in which you can only cast a given number of spells until the next rest. D:OS is based on cooldowns. Your basic healing spell has cooldown of 10 seconds in real time mode (1 turn). No beds/camps/whatever needed.
That implies everyone should have a spell (or some very specific spells) in a game that is supposed to allow for a little more freedom than that. And, yes, I'm aware there's a Warrior skillbook for healing, but that doesn't mean you should be required to take it.
Obviously the developers felt resting was needed or they wouldn't have included it in the game. I'm not sure why they removed the functionality from chairs and restricted it only to beds. I do think it would be clever if a higher level of crafting allowed players to make bedrolls.
Well, healing is a level 1 water spell. In a party of four someone would at some point put one ability point in water magic, don't you think? I mean healing was always an important mechanic in CRPGs and you should have a healer in a well balanced party anyway. If not you have to live with the consequences.
If you pick up Jahan he already knows the healing spell at level 1.
But you can also use potions. I have dozens of potions in my inventory which I never use. The devs put in beds, yes, but that doesn't mean they are needed. It's just another option to use...;)
