Or you could let people play in whatever way they find the most enjoyable. You want to run this like its a D&D day, go for it. Gonna be a lot more encounters while you short rest, which will be limited no matter what on how many times a day you can do it, and also attacks at night rough 15% of the time. The idea of penalizing a rest when someone may have gotten into a corner in the game and cant fix their level or spells and cannot possibly progress without squeezing by...in the comfort of their own home...in a game they bought - for themselves, that has no PVP or competitive component....who exactly you protecting by letting them have fun?
