I will like see

- destructible environnement
- cuztomize weapons for more performance
- sniper should be more accuracy
- gamemode with tickets cause games are very long
- news weapons
- news véhicule
- ammo bag for reload roquet launcher

Hope this will add ::)

Add grenade launcher under main weapons
Add french translation
Add squad and lock player in squad
Add setting for change grey crow
Add engineering class for build bunker trench .....

My 5 cents:

- new deployable/constructable items = wooden/brick walls and structures, movable ladders/platforms to bypass trenches
Ladders/platforms isn't possible in engine
- bridges over some buildings
Isn't possible in engine
- buildings you can enter
Isn't possible in engine
- ghillie suits
Stealth is already easy enough.
- more bushes/items for hiding (Metal Gear's "It's a box!") so AI won't really notice you even if near and other players won't see the circle on your feet
If you hide in a bush or tall grass players often don't notice you. Stealth vs. AI is easy enough as is.
- editable charachters (maybe some colours for pants or weapons)
Visual mods are clientside, feel free to customize your character via mods
- editable RPG skills (1st weapon accuracy; 2nd weapon skill; speed; health; leadership; driving ...); once you reach the top skill you begin from 0. More for a rpgish server PvP, PvPvE, Coop...
Please, no. The point of RWR is you are just another soldier, not special.
- customisation of your squad (soldier 1: 1st weapon X; 2nd weapon Y...)
There are ingame presets one can set, and enable to only recruit squadmates with certain weapons.
- ingame level editor
Already is a level editor. Ingame level editor is not feasible.
- static machineguns overheat or need reloading
Current limitation with vehicle weapons. Pasik needs to allow vehicle weapons to reload for this to happen. (I think it's a good idea)
- your charachter in the map will be a Star for instance
- linear misions
Why linear missions?
- more than 1 vehicles performing the same action for AI (3 enemy trasport trucks going together to the same place e.g.; 2 tanks invading together and cooperatively) at the beginning of the steam trailer it appears something like that and looks sweet
That was actually done with players driving. Most of the reason the AI isn't cooperating much togethr is the AI does not use callins for vehicles often, and not many combat vehicle spawns (not jeeps) exist on maps, usually.
- side missions comissioned by hidgher rank AI for you to gain some promotions or RP
I can see this as useful, as right now the armorym issions only activate during the campaign.
- light objects to be thrown (depending on how long you hold a key and the direction you're aiming rather than the position of the cursor)
Current engine limitations limit number of lights.
- missions on pitch black levels or almost complete darkness
Would be difficult without lights.

I know most of these are barely possible to make, just saying.

+1 for level editor
1 team commandant give order to squad same battlefield 2
When player level up aim better ?
Battlefield environnement can change follow battle
Véhicule artillery ?
Change weapons système for easy to choose weapons and secondary
