The multiplayer is full of ultra skilled people who have played for years, so a steep curve. Best FPS campaign ever though, so I recommend it for that.
I have found that some games like this, sometimes I do really well if only because there is such an established way to do things well that my flailing about catches people off guard. Sometimes not following meta is a shock to expectations. I'll win by sheer incompetence.
Grim Dawn is so good. If you have any interest, just go for it. I don't even play many games like that, and I've put tonsss of hours into it now. Super underrated soundtrack too, imo.
