Throwables:
Smoke grenades, flashbangs, incendiaries, maybe even knives for silent ranged kills.

Melee: Speaking of, no melees? Knives would be great for killing a enemy u sneak behind without alerting everybody and their momma’s momma.

Perks:
theres alot of potential, something like giving additional ammo, maybe a vest with extra shield but reduced speed, or pinging nearby enemies upon death would be cool.

Placeables:
Beartraps, laser like in breachers, landmines, you name it. One I would really like is placeable shields. It doesnt need a million health, just coverage to help moving across one rock to another a suicide mission.

QOL:
Mantling through windows, or up crates. Sprinting, crouching/prone, a proper tutorial, free play (solo, with friends, vs ai), pinging, quick mute

Miscellaneous:
Different gadgets from operators. Like a proximity for assault, buildable turrets from engineers (1 at a time and limited ammo for balancing, I would prolly do 5 kills per turret), Stim for medics, gives little health but huge speed increase and arms bombs faster for recon give them breach charges or something idk I dont use recon.
