Well this is a independent video game, not a DnD simulator, so yes a lot players including me will take a rest after the fight as long as it's available. Unless the game somehow limit the use of long rest, otherwise it is kinda pointless.
My suggestion is to limit the use of long rest in hardcore difficulty, e.g. long rest cost money, or u can only take 1 long rest in every 30/60 min.
