Cargo, Cyberfuck, and Cliffface are all justifiably removable. Cliffface isn't a bad map, only there's too much ground to cover in the time allotted (same with the others). Cyberfuck is too narrow on the ground, and too open on the rooftops. The only chance
Sawmill is a legitimately well-made map, however the last version opened up some rooms, etc that requires more searching and an entire Blu team that knows wtf they're doing. That extra ground really gave an advantage to props because there are more places to cover but not the adjusted the extra time. That being said, these maps won't improve just by adding time. The time limit is long enough to where the rounds are just fuckin boring as shit. Much like kakariko, and remember that kaka means shit.
