I think they should take out FMJ (especially considering that's the standard military ammo type anyway) and bring back Deep Impact. I think they should take out the "pro" parts of the perks and for most of them make the pro part its own separate perk, or include the pro with the perk from the start. I definitely don't want to see Bling go, but I'd rather them rename it to something a little more serious. Get rid of Commando, unlimited sprint, and take out Cold Blooded and bring back UAV Jammer or Camo. I also like how in WaW you could aim down your sights faster with a submachine gun, instead of moving faster while ADS in COD4. Lastly, I hope they take out the aperture sight (it wouldn't work, its basically like having a rear sight and no front sight. How would you know your weapon is lined up?). I'm not sure when reflex sights came about, but I do know they weren't around in Vietnam. So instead of apertures or red dots, a 1x scope would probably be best.
