This is more for future Halo titles than this one.
I feel that Armor Abilities and Perks should have their own place in Armor Customization instead of being part of the loadout system. This would be a big push as far as getting rid of the loadout system (which many people seem to hate) yet still giving players a unique way to play the game.
EDIT: Sorry if i’ve already posted this my computer screwed up on me and i didnt get to put up a poll
