I love Halo 4, this is just a suggestion for this game and future games.
I think we should be able to make armor sets(armor, color, emblem) and save them so we can quickly revert between our favorite armor styles. You may be able to have like 5 of them, choose a default for your service record and then each load out could have an option to choose armor and you would say use armor 3 for this load out.
I love many of the armor sets and wish I could cycle through some of them more quickly, i think this would solve that problem.
