some thoughts... not sure how into changing the map you are at this point but i noticed some spacing issues.
mid is very good... its very similar to Follower.
2nd point was basically not played on at all. it was mid and last, no hope of pushing from last and no hope of defending 2nd.

yellow means to make the yard area larger by moving everything back. shouldnt be too bad to move as the main thing you need to edit is the ground mesh.
i would also drop B area down which you may also drop the middle door to mid cp down. this gives some vertical variation at mid/2nd and also gives a disadvantage to the most direct route from mid to 2nd. high risk high reward principal.
the green - if this was an earlier stage of map progress i would move the green door over. it would open up flank routes. could be good/bad depends on how it plays in a match.

i would also extend the platform 2nd cp is on to create an opening on the inside that the defensive team can jump up to quickly. also allows quicker pushes from last. maybe get rid of the majority of that red wall.

last cp - straight forward needs more room to move around on the elevated deck. maybe even raise it up more. you want to see some solly bombs and chances for airshots.
also raise the point some... something like granary last.
