Daily and Weekly Challenges Should Come Back :)

The title says it all.
I LOVED the daily and weekly challenges.
Complete a mission on Heroic in -time- mins? Sure! Lets get 2500xp!
Or weekly challenges
Get 500 kills in warzone? Here comes the grind!
Please 343, even if they aren’t ever added to Halo 5. Give them to us in Halo 6 <3

I posted this before, but I agree with this idea:
I think it would be a great idea to have daily and weekly missions and commendations, similar to Halo Reach. The missions could be one of the story missions but with certain skulls on as modifiers to add difficulty. The commendations would be something to work for in multiplayer, similar to how they are now, but reset weekly such as a certain number of headshots, or wins in different playlists. This would increase replayability and encourage people to log on daily. The daily missions and commendations would maybe just give extra Req points, and the weekly ones would actually reward packs.
