I can't see the screens (I guess) from beta 3. Anyway I feel like FLOOR_MASTER, after some one test session (24 p, normal respawn), as the layout is quite an invitation to massive spam. Not that the point on itself did change owner so easily, but players scattered all other the place because simply the layout invited to do so. Our fear was that no team oriented gameplay was possible at all. Partial cover is really important.
As for the visuals, (but I think the future beta is about this too) I felt the lighting was unexpextedly more plain than that I expected on the central area, thus giving it a less dramatic feel. Vanilla egypt textures are fine but you should try adding some noticeable elements that would break from the yellow-brownish feel. At least make the two different sides more noticeable.
