COD
One of the more interesting aspects of Ghost are the introduction to MP dynamic elements within the maps, which range from small to large. For example: opening doors, closing doors to the evil KEM strike on strikezone.
The better ones to me are:
Octane: Gas station roof and exploding walls top of diner. Middle crate with care package.
Freight: Multiple doors that can be opened and closed
Warhawks: Field order (special streaks) mortar strike (which is a very good streak)
Stormfront: The storm that slowly appears, just cool on the PS4.
The not so stellar ones are:
Whiteout: Satellite that does very little (perhaps having it crash in different areas would have made it more interesting.
Sovereign: Halon Gas
Siege: Moving train in the middle
Personally I like the idea of interacting with maps, and its about time they added them. I presume in the near future we will see more of this, and possibly (fingers crossed) changing weather or changing day / night, evening/morning views.
