This needs to be changed ASAP. All the recent Halo games have had per match XP, and that’s what players want. The only reason 343 changed it is so that the terrible challenge swaps in the battle pass can be forced in, and so that you will buy them in the store.
When I get home from work, I don’t want to be forced to play a certain way or think about challenges, I just want to play the way I want and still progress on the unlocks.
This makes me not even want to bother playing the game, and I’m a die hard fan of the series.
