I'm sure I will think of more over time but these are things that bother me off the top of my head.
UI
- Add scoreboard and display everyone's ping
- Add compass for vehicle drivers
- Add proper HUD indicator for firing mode
- Add more HUD options, HUD and Icon opacity in particular
- Add options button on main menu
- When choosing All-out-warfare, have conquest, breakthrough and any future game modes use their own buttons instead of having to select "change gamemode" first
Weapons
- Remove Bloom/Per shot random deviation. If the player can control the recoil, they should be rewarded for it, not penalised.
- Remove first shot recoil multiplier. Recoil should be uniform for every shot.
- Increase shotgun effective range
- Remove the bullet check animation when spawning
- NTW-50 OHK range should be reduce to 10m. 20m max OR players should spawn with full armour.
- AP ammo should do more damage to light vehicles and aircraft. 1-2 damage per shot
Specialists
- Boris' sentry gun should disappear on death, not when downed
- Remove Angel's ability to team kill friendlies with loadout crate.
Vehicles
- Hovercraft health needs dramatic reduction. Should be 2 rockets max to kill
- Tanks need better gun elevation
- Tanks need faster turret turn
- Tanks should OHK any aircraft with their main gun.
- AA vehicle should be it's own vehicle type instead of taking up heavy armour slot.
Maps
- Move Breakthrough attacker spawns closer to the objectives. Too much running over empty spaces to get to the action.
- Add more light transports spawning at flags with instant respawn timer given the long travel time between flags and the number of players there are
- Option to turn off intro video/animation to maps. It was a neat novelty the first time. Now it's just annoying and I'd rather spend that time setting up my loadout.
- Orbital Breakthrough B2 either needs to be moved to the ground or increase the capture radius and height (above and below the roof) to allow for aircraft capture and capture from inside the building
