Well, Most people liked Halo: Reach's armor because you had to ability to customize more, And you also had to spend time earning credits to buy it. The armor in Reach shows a light side and a bulky side, But doesn't really have full armor sets. But other than that, Reach had amazing armor. Halo 4's armor I like too, But the skins.... They need to go. Its not like my spartan is gonna be all like, "Well, I need a skin on my armor. Lets go to a paintshop." In the middle of battle. And they have to blend in, They need to look worn from battle, Something you can hide in the environment with, Spartans go on stealth missions too.
