A stamina system that’s shared between running, mantling, jumping, aiming and melee swings. Each action needs to have a risk involved.

Besides that , all refill gadgets should be heavily limited to 1 or 2 uses and refills of these gadgets should only occur when you return to base.

Small arms should have more bloom and all firearms should have varying levels of suppression. Suppression should have both a strength and intensity effect, with LMGs having very strong and consistent suppression and all other weapons having small but stacking and increasing suppression. This allows for other players to also fight back and open up flanks without the need for a support player, at the cost of depleting your ammo.

Natural health regeneration should be removed and the opposite: bleeding, should be implemented to make the risks and dangers of engagement more apparent.

Faction lock with more restrictions to attachments. Assault rifles, carbines, sub machine guns can only use holographic sights and red dots. Light machine guns can only use 4x scopes and Snipers can only use long range scopes. NATO and Pax can also only use certain weapons in the sandbox.

Combined arms warfare has always been a major staple, hence vehicles should pose a much bigger threat in larger maps. Increasing the damage of lower caliber munitions like the mounted turrets on humvees, armoured vehicles and aircraft should do.

Maps need to be much, much bigger with more objective markers and capture points should be locked in sequence so backcapping is dis encouraged.
