The area up there is not really highlighted or used. In the last game there was a little demo spam or heavy harass, but nothing significant really happens here.
Also, after capping the point the natural thing to do is advance into the buildings. They are really easy to camp and it's just one step away from actual spawn camping. The map simply needs to be larger, despite it's higher and lower areas (the lower areas of which didn't seem to get much action).
You need to provide more oppotunities for people that capture the point that doesn't involve advancing on the enemy spawn.
