Well, I've been playing for a little while now with Patch 5, & can honestly say that I like the direction that the long-rest system is taking, & I also do like the whole "mini-camp" thing, & would actually like to see it become the "default setting" for all long-rests (i.e. your long-rest setting will always match where you chose to take said long-rest).
My only recommendations for improvement-in relative order of importance-might be:
1) Have a minimum resource cut-off for taking *any* kind of long-rest (even partial)....though that might be good to tie in with the in-game difficulty settings. This would make the decision to take a long-rest even more strategic.
2) When outdoors, allow characters with appropriate skills (like hunting or herbalism) to increase your resources levels as part of the long-rest process. Likewise, allow characters with the appropriate skills to disguise your camp & stand watch prior to long-rest (see point (3) for an explanation.
3) I will probably get howled down for this, & I would understand if you rejected the suggestion, but I'd like a small chance for random encounters to interrupt a long-rest session (as an old-school D&D fan, I always loved the whole "Wandering Monsters" concept!)
4) I know this may be very difficult to implement at this point, but I would still love a full day/night cycle within the game, & thus have long and short rests move time forward within the game.
Anyway, those are my suggestions. Other than that I am loving my play-through with Patch 5. Its already playing out considerably different to my first 2 play-throughs.
