Progression/assignments - I don't think I hear anyone talking about this

I enjoyed the beta, the one unknown I want to know more about before I make a decision on buying the full game is assignments and progression. I really enjoy having to complete specific tasks to unlock weapons, attachments, gadgets, cosmetics, etc. I remember having to do specific challenges to unlock new weapons in bf4 dlc. And when i returned to bf1 after the release of bf2042 i enjoyed working towards the four horsemen dog tags, though i didn't finish them. The beta showed some promise with the challenges for unlocks, but I'm worried about how the season pass will play into this. I don't want every unlock to just be based on how much xp you got that season. How did they do this in bf2042? I'd much rather have a dog tag because I've completed a really tricky challenge than just the level 20 season pass reward.

This kind of thing is what keeps me coming back to the game. I want them to conver a range but for at least some to be quite specific and tricky. Do others feel the same?
