I am with every one here on wanting a more legitimate ranking system and it needs to actually earned instead of handed to you like you're playing T-Ball. I have long felt that the numeric ranked should reflect the "ranked" playlist and the military rank should reflect the "social" rank and your "global" rank reflect both, say a 45 - Commander / 50 - 5 Star General. I differ with some in that I want to see armor earned as well and if credits do some how survive, use them for attachment, armor colors, visor colors, wear and tear effects on the armor, etc.
The Daily and Weekly challenges held little interest for me, but most really enjoyed them. I expect they will be the norm from here on. My lack of interest may have been because I despised the credit for rank system.
I agree with HaloScreamTage that 343ind. needs to strive for excellency.
