Yeah, that's what I meant above. It just looks like he's wearing an under armour type spandex layer underneath with random pieces of metal slapped on. The shoulders are the thing that irritates me the most, but so is the chest. Doesn't really feel like a cohesive/unified suit of armor that can regenerate health, withstand bomb blasts etc.
I understand why they want to make changes (I love the old look more), and they're free to do them. I just wish they had done it better and also explained it in the story. I think their helmet designs were the worst. Random shapes, weird eyeholes/visors, Halo 3 helmets were the best.
You never know though. Bungie went from Mark V, to Mark VI and then changed it a bit again in H3, maybe 343 will do the same, especially since it seems his visor is cracked, armor is all damaged looking, maybe they'll have him be given a new set.
