People who do not like "to get stressed" can just ignore it.
I just hope they will not add any mechanically completely meaningless "you need to do some more clicks before you can rest" rest systems; I like when games do not add unnecessary chores.
Then why are you playing a cRPG?
For exatly the "c" in cRPG and not to watch the party walk 5 minutest to a "safe" location or to do the same repetitive clicks every time I want to set up a camp.
The only way to add some mechanical relevance and not just nuisances to the resting system ARE time sensitive events and/or achievements.
