Simple ideas:

When creating a server, server owner has the ability to select two things:

Either A. Warmup Round or B. Actual Round

Warmup round is just a simple match, not CTF, just killing free for all til enough players are present to start an actual match.
Maps generated should be fun and odd (floating islands, odd shapes, various colors, etc.)

That way, the players can all start a match at the same time, rather than entering a match that already has towers built everywhere with decoys giving the new players no idea where the intel is.

Other stuff:

Have the ability to give away the position of an enemy that killed you.

I'm not asking for a killcam (although it would be nice to see if the player is botting)

Just a simple exposure to where the enemy was who killed you.

Example: your body falls over, but faces the direction where the enemy killed you from, the enemy is marked red with a little arrow pointing down upon him to give you an idea.

i like the other stuff ideas. The pre match stuff is a bit iffy

It is very like COD BlackOps.

This game should not be complicated as it is not that sort of game.
