So apparently the maps in Ghosts are going to have traps and dynamic events (I remember seeing a flood in one video and earthquakes being mentioned). Ok IW if you want to add traps and dynamic events, take out the exploding red barrels and exploding cars. We already have enough to worry about without worrying about which car or red barrel is going to randomly explode.
If I can't kill my teammates with the traps, then I am not interested.
In BO, you could get your teammates with barrels, even in Core mode. Not to mention the bridges on that one snow map that you could blow up as your teammate walked across them.
