It's easily the worst map. Going slow through a map and shooting mines on the ground just is not a fun game loop IMO. I rather it get replaced by something else. I'd rather have more soldier patrols or a helicopter you have to hide from and escape to apartments.
Edit: Most people are missing my point. I don't think it's hard. I agree the mines are easy to spot and go around. That isn't my point. I just find it boring and tedious. It's a chore and not enjoyable.
