Here are my ideas for spawning, the mcc, weapons, installations, vehicles, aircrafts, boats, drones, miscellaneous and steering.
Sorry that many ideas are still brought in by others but my ideas are a really complex system so otherwise id have to link my posts always. I hope you understand this.

Spawning:

Mercs shouldnt appear out of nothing but drop in. When you choose your spawn point you see how your merc walkes out of a main CRU and gets picked up and carried over your spawn location by a drone. There it circles in the air until you jump out or it is shooten down. The clones have disposeable windsuit to steer and slow their fall. If there are enemies under you you can press a button and the drone takes you over the next allied. The drones have just energy for a short time and throw you out if energy is nearly empty. If you choose the hangar or a deployed CRU as your first spawnpoint you just walk out of the CRU.

Ordered vehicles were produced on the MCC and picked up on a production line by a RDV. Ships were brought to the next waters if you are on land. If you order a vehicles or aircraft in the hangar they just roll from the production line.

MCC:

There shouldnt be just one version of MCCs. One of each faction and different levels would be good.

The current MCC doesnt fit to any racial ship style. It looks like Gallente but it has a stronger shield like Caldari or Minmatar.

The battle should interact more with the MCC. There should be a spawnpoint just for attackers on it. On the top should be a hangar with a CRU, some factories for vessels, a few turrets on the outside, a small hangar for spawn drones and RDVs and a repair unit. You can see how vessels come from the production line and mercs walk out of the CRU. There should be a similar hangar just for the defenders under the planets surface in their non-hostile area.

Instead of waiting for other players in the war barge before a battle they could choose their dropsuit directly after choosing the battle and wait until it starts in the hangar where they can already call in a vehicle . Of course there are also fitting and market desktops and a hologhrapic map.

The MCC should be more customizeable by the corporations.

Weapons:

There should be more types of grenades like EMP-Grenades which paralyze mercs and vessels, nanite grenades which create a fog with nanites that damages everyone inside it, smoke grenade or dazzle grenades.

There should be more types of melee weapons like tasers, poison injectors or just fists.

There should be more types of sidearm weapons like a flame thrower, a nanite sprayer that work like a nanite grenade inside or an electric pulse battery that creates a flash which jumps to every metal part within a certain range and paralyzes mercs and vessels and this a few times until its energy isnt strong enough anymore.

Weapons and turrets should have customizeable parts to increase some stats or reduce PG and CPU cost. We should be able to change the mag to increase ammo, the loading mechanism to increase rate of fire, bullets to increase damage and range, barrels to shoot more accurate and increase range, muzzle to decrease its recoil, noise and muzzle flash and the hull to reduce weight. Those that increase stats need a lot of CPU and PG so you can mount just a few or mount some that take fewer PG and CPU than the standard parts to make the weapon not too PG and CPU expensive. Different types of scopes are cheap because they give just the ability to personalize and some to zoom. There should also be additional parts which replace grenades, sidearms or melee weapons. There should be melee weapons which replace the normal melee weapon and are mounted on the muzzle, launchers that replace grenades and are mounted under the barrel and special weapons that replace the sidearm weapon and are mounted on both sides of the barrel. They have the advantage that you swap faster to them respectively they throw the grenade farer.

Installations:

Those should be in the game:

Walls
CRUs
Different Weapon Insatallations
Bunkers
An self enfolding barrack with space for 4 mercs who can shoot out of it.
Tank Traps
A barrier which cannot be passed by tanks. Like those which are already in the game beside the road in the skirmish map.
Personal Locks
A barrier like a barbed wire entanglement which cannot be passed by mercs.
Radar Stations
Shows every enemy within its range and marks them. Marked enemies are shown on the HUD with a symbol depending on its class.
Drone Stations
Drones can refill energy there.
Autoguns
A small turret with a light weapon that shoots at every radar marked enemy within its range.
