I had the same feeling after completing, so I started to play ranked to get a sense of progress and try to improve and climb while playing. Try it out and see if you like it. Other than that, I do the weekly’s, but yeah - a progression system other than the battlepass is badly needed.
I finished my battle pass yesterday. Needed to get all my unlocks done to justify the price.
Plan on taking a long break until they fix the servers, server selection, ditch the rotating weapon spawns and ditch SBMM for non-ranked play.
