This is basicly what I think would benefit halo 5.
ranked and social playlists
visible ranking system:for all of those people that cant live without it (you know i love you)
interactive maps
all the gametypes from past halo games available in custom games
interactive forge objects
moving forge objects
any weapon/vehicle that cant fit in the multiplayer should be in forge
an option for duel wielding in customs
the ability to turn of sprint
sprint being taken out of normal slayer and only allow it in BTB
take away the flag carrier’s pistol, but let him run at a normal speed
the return of invasion( i love that gametype from halo reach ) and any other playlists that shouldve been in halo 4
i think that halo 5 should be an arena shooter first so no custom loadouts
remove ordnance drops from slayer but keep them available in custom games
add the option to increase or decrease the speed of a vehicle by going through its options
anything that was missing in halo 4’s forge
more custom game options
the ability to disable a vehicles gunner in forge (like ghost that you can drive, but you cant shoot)
firefight
the ability to create ur own firefight maps
the ability to mix firefight with objective and possible make ur own missions
bots
ordnance fire fight (after killing a certain amount of enemies or waves, u can summon an ordnance but you can also choose what u want in that ordnance in the pregame options thingy)
hard core firefight( something thats similar to the firefight in halo 3 odst
EDIT: here are more suggestions
a slayer variant where you can choose ur primary weapon only
no more perks
armor abilities can be found on the map and u lose them when u die
make overshield and camo armor abilities that can only be used once before becoming useless, also make camo the way it was in halo 3
thats all i got for now… please add ur suggestions below, and btw
YOU WILL READ THIS SENTENCE!!!
PS: if someone who works at 343i sees this, please reply so that i can feel awesome
