I’d rather just see the equipment from Halo 3 return to be honest… with more equipment choices… maybe custom equipment traits? Like you can make it so powerdrain makes your shields go down at 10% per second but you’re invisible… and have 150% weapon damage… so anyone can shoot you once in the head but you’re kind of invisible for a little bit… and can kill people in one shot less… as long as you’re by that powerdrain… could be good with snipers… you’re a one shot but so is everyone else (to you anyway) 
Just an idea… here’s some options I’d like to see:
Radius of effect/equipment
Duration of effect/equipment
Weight of equipment (will it fall at your feet or roll 8 feet in front of you down the hill?)
Health of equipment (how much damage it can take)
Size of equipment (can get as big as you want within reason)
Waypoint above equipment? (Well it could come in handy if you’re building a huge radar jammer and now they’re all running toward you with nothing but their eyes and ears;)
Number of uses (maybe you want to make something like an AA… now you can set how many times the equipment can be activated before you lose it… the default is 1 use)
Time between uses (Again… just for the AA type uses…)
Effects: (these would work like checkboxes in that you can have multiple at once and they all have their own traits
Base player traits become: (goes to a submenu where you can customize traits that last even after you’re out of range of the equipment. You can set the duration for this.
Invisibility (options include Poor, Good, Perfect, and Reach. Perfect means you are completely invisible… no transparent textures… just poof. Gone.
)
Radar Jammer You can customize the dots, how fast they move, how they move (circular motion, straight lines, figure 8’s, mixed… realistic… ect.), if there will be multiple colors, and if enemies will still appear on radar.
Bubble shield: Options include: Radius, health regen/degen, and whatever else you can think of:) just add Base player traits within//
Yeah I’m done for now… but you get where I’m going with this…
Radial Base Player traits: Just the player traits within the radius.
So let’s say you had a game of something like duck hunt… you could make three equipments that acted similar to bubble shields that could be reused 3 times with 4 seconds between uses and they expire after 6 seconds. But one could just make you invisible instead of protecting you… one could make your movement speed faster and protect you but you’d get less uses… then the standard bubble shield… the camo one would be purple… the speed one would be red… or whatever you wanted… idk your imagination is better than mine:)
