Battle pass progression

So in the news tab of the game they talk about how the new system will take time and they’re working to change it.

I get overhauling part of the game does take time but how hard is it to do a system like CoD’s battle pass where you gain progression from playing based on performance as well as a bonus from completing challenges. I feel that a change like this gives everyone what they want. We get a more enjoyable grind and progression and 343 still gets to sell us challenge swaps.
