What's "complicated" about it from an user standpoint?
"Find a spot large/plain enough to place a temporary camp, be sure to have some supplies in inventory". Done. Have a nice rest.
Not exactly rocket science, uh?
There's some more optional stuff if someone REALLY wants to "fine tune" it (who's standing as a guard, who's cooking, etc) but for the most part the default "auto-setup" does the job just fine and it doesn't need any additional player input.
Well you have to collect food or in case of Pathfinder buy Rations so you can survive a excursion into a Dungeon because no Hunting in Dungeons. So food eats a lot of your space and gold.
And then if you have a live outisde of Computer Games you are coming back to an save game went into a dungeon just to find out you have to go back because not enough food and so on and so on.
Or the exploration of a Dungeon takes more time you cant get out for some reasons to get food and so you cant really rest but the enemies are hard so you have basically no chance anymore....
In my opinion, way more frustration than immersion.
But it depends how exactly Larian will implement it. Lets see.
