Subway needs a rework / balance adjustment

Subway is one of more older virus maps, and it unfortunately shows.

It’s a very large map. So much so, that its pretty hard for the infected to get a start.
It’s much too open, and has hallways that are far too wide.
So I’ve been thinking, why not cut its overall size in half? And while we’re at it, a bit of a visual boost?
Close off a few corridors, narrow the hallways a bit more, maybe even add a “destroyed” vibe to it and bring some of the structure down to serve as cover or paths. Besides, it doesn’t make sense for there to be a perfectly working subway in an apocalypse.

Virus is about the infection just starting to spread, so it does (I don’t understand why they made that weird postprocessing though)
As for the map size: I don’t think you’re right
Subway map always suited for me and my friends when we were playing in full matches with like 12 people.
It works worse when there are like 5-6 people, but for that we use smaller maps like Desert
