Yeah I noticed that one, too. It was in BG as well. I think it makes sense. However resting before every fight I think is stupid, too, especially since it takes you out of the current situation on another screen and then back again. It is a time sink. Also there is no time passing in the world we play in. Limiting the amount of rests is not a good idea in my book, because managing your resources in a fight is already hard, doing so over multiple encounters is cumbersome and inconsistent. I prefer either the PoE concept where most skills are per encounter and only a few require rests. I would also prefer to have all skills and abilities ready in every encounter, makes the game perfectly consistent, which I think is the core priniciple of having a good game flow. Right now Shadowheart ranges from an exceptional valuable companion to rather useless depending on the status of your resting. In any case it seems they have something planned for it, and I guess exhaustion is one of those issues, you also have the short rest option, which is now obsolete, since you can rest with no penalty. Also Larian advances story elements mostly in the camp, so if you do not rest you might miss crucial stuff, which is another odd choice.
