Do You want to have to play through hours of matchmaking (basically making it a chore) to buy armor like in Halo Reach? Or would you prefer the way it was done in Halo 3 where you completed certain tasks (beat campaign on legendary, get all achievements,etc.) to get armor. Let your voice be heard so 343 knows what to do!
In case you didn’t know, I want it the Halo 3 way. 
Neither, everything should be there from the start.
Not that it will be though, these rewards are designed specifically to hook the player.
i liked more the Reach style, but since the game is pretty far in development i doubt there is anything we can do
Reach style cause it’s easy to get cR… but it takes a special type of boosting to get achievements and well… I don’t feel like getting people together to cheat for armor.
