I don't know how these maps can be considered worse than MW2019?
I mean, Picadilly, Euphrates, Azhir Cave, Palace, Ramazza... they were unbalanced and terrible. Crash was a camp fest because of the way 2019 played, it was god fucking awful. Vacant was a ho hum MW1 map, but one of the best in MW 2019 because the maps in MW2019 sucked. Shoot house was beloved for the same reason, I thought it was a simple small size map but everyone revered it, likely because most of the main maps were trash.
I think Grazna was decent, though camp friendly. Gun Runner was good but frankly I somehow was terrible at it. Hackney Yard was the best map imo.
I played the game and maxed the first season, but then after a while I got so pissed off at the general camping and map design I ejected the game and never played it since. Good mechanics, terrible maps and everything favored camping.
