Scale isnt to do with the shape of the map, it is the size in general, from the dev texture squares i calculated that your mid is somewhere around the 3-4 thousand hu long mark. and you have a sightline by second that is 3684hu long. also the lobby area by 2nd looks like it is 1500 x 750, and it has no cover at all. Also, in those screenshots if you look at the size of the 2nd point compared to the surrounding area, it looks tiny!
