A complete revamp, as the current formula is tired other than the control fluidity, which is unmatched anywhere.
- A future setting, where bullets are obsolete and replaced with gauss, laser and plasma weapons. Possibly post-apocalyptic?
- Vehicles you can use from the start, not as killstreaks. However, the vehicles shouldn't be overpowered as they are in Battlefield 3
- Specialist-style killstreaks that improve your avatar's combat effectiveness as you get more and more kills without dying, but with the trade off of an increasing XP bounty on your head as your killstreak builds, including notifications of enemies being on a 5, 10, 15, 20 kill streak etc, as in Halo
- Greater customisation options than just perks, including radar jamming, armour and extra speed (but with tradeoffs so you can't be fast, stealthy and tough all at once, for example), leading to significantly different builds for each player depending on play style
- Larger, more open maps to accommodate the vehicles, otherwise it would be overly congested! This would also solve the "I'm stuck on sh*t" problem MW3 has if you run and gun. However, have some smaller maps for those that don't like having to think about enemy tanks or air support
- A STRICT over 18 policy, so no whining kids (I'm nearly 30) - to this end make it so violent and full of swearing no parent in their right mind would buy it for their 10 year old son / daughter lest it give them nightmares or warp their minds
- Rewards for scavenging and using enemy weapons to get kills (like Black Ops had)
- No motion sensor or portable radar (like in MW2)
- Invulnerability for between 3 and 5 seconds after spawning, to stop spawnkilling
- A completely destructible environment, so that campers can be blown right out of their hidey hole if found. Plus, if a person gets killed by a collapsing building or landslide caused by an explosive, the person that triggered it gets the kill.
And finally... no sketchy hit detection (Black Ops) / counter-productive lag compensation (MW3) / "revenge spawning" (MW3) / quickscoping (all CoD games since CoD 4).
Rant over.
TL;DR version: A big change to the game.
