Please let us level up previously purchased season passes
Halo is already doing this, and the season passes are free.
I've paid for every single season pass up until now, yet only recently have I had the time to grind out 100 levels. It'd be a huge quality of life improvement if we could progress in previous seasons while we wait for Witch-Queen. I'm already over level 100 this season, so I'm kind of running out of stuff to do. Plus I already purchased those seasons, so I should be able to progress through them and claim what I purchased at any time. It would be easy good press. You could even sell the previous seasons at a discounted price as an incentive for players to keep playing.
I know it isn't likely that anything will come of this request, but I'm already kicking myself because I missed out on those seasons because I didn't have time to play. If I don't say something, nothing will change.
