343 is open to suggestions when it comes to how experience/ ranking system could work I have some ideas. Experience system seems strange that playing games will not give experience, but idk how the challenges will exactly work hopefully the daily challenges are some that you easily get by just playing. You should not have daily challenges hinder how game types are played. As far as rank I have a lot of idea that are better then just a number. It looks like Halo Infinite is really trying to sell the idea that your Spartan is part of the story of Halo and it only make sense to use UNSC ranking system like in Reach. I utlimately think leveling should be similar to MCC ranking system. I understand that MCC has a 11 tier system and for a game that will be around for at least 10 years 11 won’t do. So first instead of it ending at General grade 4 take the ranking system from Reach go all the way to Inheritor. Then from Tier 11 to Tier 10 instead using two swords 
in between colors do one sword 
then two. Now this is a bit out there, you can include other weapons from Halo like gravity hammer(s), BR(s), DMR(s), sniper(s) and so on. Then you can other colors after blue in tier 2 like any and all colors. Then you can take the shield 
outline make one side one color and the other side another. Then for later tiers you can have the colors rotate clockwise, then counterclockwise, then fill in the shield with one solid color, after that do two color inside the shield , and then finally you have the two color fuse like the visor colors move in MCC. Then for rank it’s simple just follow Halo 5 it’s perfect. Hopefully this all makes sense if it doesn’t please do ask me to explain further. Thank you and if 343 is interested in doing this please help me get Halo Infinite series X console at retail price. Please
