Yea, the Halo 4 and 5 armor was quite bluntly hideous, with darned few exceptions. Infinite brings some decent armor back into play, but I find this "armor core" nonsense infuriating. I want to be able to mix and match ALL armor pieces across all "cores." I'm enjoying that MCC has not only "retrofit" a lot of armor into other "generations" (although I'm not sure how I feel about this "viking plate" gimmick) but also added new categories to the older games (e.g. legs and forearms to Halo 3). Having fun with that although my options are limited (the freakin' GRIND, man....I hate it).
An amazing armor set. I just wish you could wear it sooner. Level 96 on the battle pass to get the Postor armor of the game is freakin stupid if you ask me. At least you don't have to pay for it.
