On bears i find that wolves and black bears become quite manageable by back kiting even with simple leather armor and a good iron falx, but brown bears in particular are tanky and fast making them really oppressive, which wouldn't be that bad if they were rare or easy to spot - but they are neither.
I find them really tedious to deal with and would rather avoid them but they are such a pest i have no choice but to kill them and now i have more leather fat and meat than i can use.
If i don't kill them an unexpected brown bear attack is almost always a death sentence due to how persistent they are at chasing you until you are dead, i wish they had stamina and tired down after a minute or so to allow you to shake them off eventually.
I also have an issue with their weird hitboxes that make them harder to hit while running.
Overall just not a fun experience when brown bears are mindless killing machines with overtuned stats and being so common, they don't feel polished or engaging to combat.
