Add: Spawn Options (during killcam you could either spam respawn and get a random spawn or hit select and it brings up the mini map allowing you to select from a couple spawnpoints around an objective you have under control.)
projectile options, as in tomahawk, throwing knife etc.
Remove: deathstreaks (so obvious, at most give them a ballistic vest, or a speed boost, or hollow points. No falling on your ass or pulling out super c4)
Keep: Support killstreaks, weapon proficiencies
really it comes down to tweaking what they have already. They don't understand what they are doing and it is beyond obvious. Community playlist should be a real playlist for example, not one game mode you change some times. give us all the private match gamemodes in the community playlist. When patching ONE weapon (fmg9, you crybabies) don't patch the other weapons in the same category for no apparent reason (skorpion makes me sad now

) and obviously fix the spawns. It feels like shipment on every map the way they spawn with you in their sights.
I also think crouch to prone should be a delay (drop shot bitches) and stop designing maps for head glitchers.
also elite is a let down currently. However if Activision lets treyarch do its thing (lol that wont happen) I feel liek we'll get the DLC fest we deserve. They make so many maps that never see the light of day.
