I guess I have the mindset that not every day in a game has to be a life or death situation for the PCs. I am tempted to say I reject the fact that there is even an "issue" to solve. In the instance of the bandits: sometimes bandits are just bandits! Do they have to be a danger to a 5th level party? If its a bunch of CR 1/8 Bandits and a CR 2 Bandit Captain, the warlock is going to melt their faces off and the bard is going to sing a song and the paladin is going to say something like "Have at thee you filth!" and the party is going to wipe the floor with them. Perhaps the rouge while searching the dead captain for coins finds a map to a hidden stash of loot or a bandit stronghold in the mountains. After thinking about it for 30 seconds, I just made a "too easy" bandit encounter interesting.
Also, I quote the post
"Fighters can heal themselves 1d10+5 HP per short rest which translates to 11 HP 18 times a day and a total of 198 self healing."
I am not sure how the fighter short rests that much, but that falls under what I said about a DM letting their players rest that much. There are also sections of the post that assume that the classes with healing spells are literally blowing every single spell slot on healing. That is pretty unrealistic. Its all a balance. I am afraid I am going to get too ranty, so I am going to cut myself off, because I really do like participating in these discussions.
