I found this game great, but I also think it needs improvement about resting system.
At this moment one can go long rest after every battle, which make some spells like "Prayer Of Healing" quite useless.
I think it would be a nice idea if the game will check safety of the area and make you to roll dice before resting (1d20 for instance), and if you fail it will cause a problems like an ambush in a camp or something else. Furthermore, maybe some areas (caves, Underdark zones, instances e t.c.) should be even prohibited for resting.
