I posted this list on another forum, I thought it would be good discussion here

What I would like to see out of MW3 is:

- Better hit detection; Nothing worse than being completely around a corner and dying afterwords from the "curving bullet effect"
- Better sniper rifles than Black Ops, but no quick scoping
- No akimbo shotguns or submachine guns; only pistols
- Return of the tac knife, without commando
- Make the tac insertion like in Black Ops, where you can delete it, but allow the user to view the spawn area before spawn to prevent spawn killing
- No stopping power or juggernaut
- No death streaks
- At least 5 sniper rifles, with an even distribution of bolt action and semi-auto
- Option to have ghillie suit or not
- No danger close
- Better response to overpowered weapons *cough* UMP *cough*
- No heartbeat sensors/motion sensors
- Ability to have equipment and lethal grenade (ie C4 and Frag, or Tac insertion and semtex)
- No stun grenades
