1) Implement the same spawnwep system as it is in the XE so we can choose all the weapons to spawn with. None of the sets suit to my play style so EVERY time I spawned, instead of immediately joining the fight I had to find a quiet place (since you can be easily killed at a spawn points) and type in the /c wep commands.
This is one of the reasons why most part of the game I spent outside of the base -- getting killed by a group of enemies right after all this typing is very annoying.
There is a client-sided solution - macros. But idk if that's allowed, and that would involve spamming commands at a quick rate.

2) Increase the initial and '/c wep' ammo count to max. I use m4/ruger a lot and run out of the default 500 very quickly. Watching at ammo/refilling is just a too big of a blunder. Again - instead of playing the game I get to practice my typing skills...

3) Do not spawn the vehicles inside *each other* (barracks at blue base) as it creates ENORMOUS lag. Every other part of the game ran smoothly at constant 30fps and only Prawn island lagged like hell. Because of this lag the only option for me was defending.
If I remember correctly, spawning them in walls should be fine, the problem appears when cars are spawned inside one another. I guess the game starts to calculate collisions but cars can't be moved so these calculations go on forever, hogging down the CPU. Also the same result could be achieved using an invisible barrier like in SvM (you get pushed back when try to leave the island). "Get a better PC" isn't a solution!
