Considering you can spawn trap and kill on even the massive maps in MW, it doesn't surprise me this one is a nightmare. Rust in MW2 worked fairly well and users always had some form of spawn protection and trapping was rare - at worst you die to a random nade but otherwise even with someone on the top of the structure, it was so rare to be spawnkilled.
They could've chosen High Rise, Afghan, Terminal, Sub Base and Scrapyard but they go for the fad maps which are only good to escape the exhausting big ones and for quickfire fun now and then. They'll probably release Free Fall from Ghosts next..
Also well done to Lee for expanding my original post with all the confirmed details!
