I understand you but that change was not that drastic as what 343 did for Halo 4... Exoskeletons or not, they change too much in Halo 4. You can't change something that has been for 10 years in games and boom have something totally different! The change that Bungie made was significant and maybe people who are very into details (like you) noticed it and didnt like it. Yet it seemed similiar to what the studio made in first place.
