In my opinion i think it would be better to not release it as some people get things like LASO done legit, and some just get the nameplate via glitches making them butt hurt and me being one of the butt hurt people as i got Halo 4 LASO done legit, but thats just my opinion.
While the map is loading, hover over the nameplate/avatar/emblem you want and just tap 'A' a couple times til it goes to the loading screen and when the game is over (or you quit) you'll have it selected.
