If it were me I would:
1. Remove some of the canal north of the middle VP (as above). It would not take much. To give the north army a bigger area to spread out.
2. Remove the small building overlooking Left VP. When pushed the bottleneck it creates makes it hard to defend that area.
3. Remove some of the high fence south of the left fuel. And possible add a wall or some other cover there. When pushed south team has no cover just a large road area.
4. Remove the two large cargo containers just south of middle VP. Use something that can be destroyed by mid game. It creates a bottleneck when defending middle VP.
5. Rework the area just northwest of the middle VP. It is a cluster and creates vague engagements.
6. Remove the stupid sight blocking shrubs north of the middle VP. Derp.
That would be a good start....
