I am sure Larian will add day and night cycle to the game. I mean it is 2020 and thinking about a serious cRPG without night time is absurd.
Also, I red somewhere in the forum some one suggested random encounters and attacks at camp at night. It is a wonderful idea especially when you camp in more dangerous areas further in story.
However, camping system in EA is terrible and totally immersion breaker. I mean having the ability to have a long rest wherever and whenever you wish after a fight is just cheating.
Rests need a reworking, yes. I doubt they will remove the transport to and from the campground, unfortunately. Day/night isn’t happening.
