In summary, the overall difficulty seems perfectly appropriate. However, some things are currently too strong (jump, shove, barrels, maybe backstab?), some things might be too weak, some things are bugged which affect the difficulty. These should be addressed but overall difficulty seems just fine.
I also appreciate how there are generally easier and harder ways to do things. Do you want to face enemies head on or perhaps use that side path to get past? A lot of the fights are optional, or can be arranged to be easier somehow through story options. I like it when I see that.
Hide as a bonus action for everyone is also very broken. If you really try to abuse stealth with ranged + hide + line of sight you can solo the entire EA.
