These are a couple of ldeas I've made up of my own
*No Stalker/Pro (Aka Steady Aim on Steriods).
*No Stealth perk thats immune to almost EVERYTHING!
*Bigger, More open maps. MW3=Pacman with Guns.
*Lunges that don't make people twirl like ballarinas(sp).
*Fix Headshots in the legs.
*FOR PETE SAKES Fix Panic Knifing.
*Annoying Aim Assist.
*Not to be lasy when it comes to patching things.
*Left 4 Dead kind of Zombies (IMO).
*No Host reliability lobbies (Aka Deticated Servers).
Post More or Complain about Some.
These aren't really ideas, more modifications.
I agree with everything on the list though, besides Stalker's removal.
