1. I don't mind bloom, but after playing Halo 3 and how fast paced it was in comparison I would like to see it go.
2. I liked Armor Abilities a lot with the exception of armor lock in a non-vehicle/explosive context. I would really like to see them return as well as equipment. I think it would be awesome to have an energy sword and use a grav lift to take out a guy who tried to jetpack away. I think they can return but with a better balance and such. Evade, sprint, and armor lock can go, but I liked the addition of jetpacks, holograms, invisibility, and such. What would be really good for these is a limited use per life, kind of like equipment. You can use hologram 2-3 times, you can be invisible for a total of 20 seconds in a life, you only have a set amount of fuel for jetpacks. I think that would really balance them out and make them more similar to equipment from Halo 3, which should for sure return like the bubble shield, grav lift, power drainer, and trip mine. Balance them out, fine tune them, make them all pick ups rather then starting abilities. I just want to see their presence in the next one, but I wouldnt mind if they didnt show up at all.
3. Approve. I liked how certain guns had more powerful melees like the brute weapons and gave you an incentive to close in and melee. Gave guns a unique identity outside of its ammunition
4. Yeah, I prefer all the DLC maps/cool forge maps over the standard ones. I miss when maps weren't part of the campaign, and they shouldnt be.
Halo Reach was for certain an awesome game, and it brought a lot of cool innovation to the series, some of which should stay, and some which shouldnt. Halo 4 should be the ultimate pinnacle of the series so far because of how different 3 and Reach were
