I would like to have the Brutes appear in Halo 5 again. They don't have to be a foe they just gotta be apart of it in someway, they were just too awesome. If the brutes do make it back, the halo 3 brutes would be amazing but with the size of the halo 4 brute in the first cutscene.
Fixes:
Armor;
The armor looked a bit plastic and it glew a little more than needed. The halo reach armor was pretty cool even though the game had a low rating. In the dark I could easily see the enemy but I would like to look for them in the dark. The armor should also have a standard issue instead of a but load of different bicep pieces, just have two or three that shoulder pieces can attach to. The shoulder pieces were pretty amazing in halo 4 but like I said before they looked a bit plastic.
Armor abilities;
The armor abilities were alright but they were a little much. For example, the Thrust Pack was just horrible lol I'm sorry, but it didn't really serve a purpose, evade was far better. Really Amir abilities kinda of ruined the pro gamers thrill. I'd actually like to have halo 3 pick-up equipment.
Vehicles;
lol do I need to say more. WE need more vehicles. Also could they be a possible boat variant added on. (Since Spartans cannot swim in water.)
Campaign;
In campaign the Prometheans were a very nice spin to enemies but!, they were predictable. Also the campaign was tooooo short. I beat it in 4 days on legendary would have beaten it sooner but my consolation armor got in the way.
Map ideas:
there could be changing weather in maps. Such as, when there are long battles the daytime slowly fades to night and if its a night map it fades to day. A problem In the maps like I said before is that they were too light, even if a forger tried to make the map night time. Also if its not to much could they be raining weather map, snow maps, sandbox map, or a forge world map.
Multiplayer: weapons/ animations
Could there possibly be some way to add the old weapons back along with new ones. I have never came across a game that got rid of weap
