I added your map to the official EU servers. After playing it once I can say an alternative way for attackers to reach the flag is really needed. Defenders can stack construction sites and camp the door, making it almost imposible for attackers to have a chance. I would suggest adding a stair between the roof and first level of the keep, so attackers can access the roof from outside by ladders and actually be able to get to the flag. Currently jumping inside from the roof is pretty much lethal.
Looks a lot better now, saw attackers winning from time to time, defenders still have the upper hand though. About that, correct me if I'm wrong but defenders spawn only inside the flag keep? If that's the case, adding additional defender spawnpoints on the outer wall and in the courtyard would balance it out, since defenders wouldn't always spawn near the flag.
You need to rework that map a bit. Defenders win always on this map.
The entry to the flag is spammed with construction sites often attackers dont even manage
to kill the door to the flag.
You could get rid of that whole building and map could be balanced i guess.
You could try to remove doors of the buildings.
You could remove defender spawns near flag.
You could add 1-2 additional ways to flag.
