Can we please get a leveling system seperate from the battle in reach with possible rewards

In Halo reach we had the leveling up system where the aim was to reach inheritor but in infinite we have nothing other than a limited battle pass. Please could we get a progression system seperate to the battle pass possibly giving us exclusive cosmetics or something at certain level. It doesn’t have to be many but just a couple then when we have finished the battle pass like me we can have something else to work for in the multiplayer aspect of the game.
