I agree with the overall feeling here. IMO I think one of the issues could be how close the objectives are to each other. I've exclusively played Rush and Breakthrough, and I understand those are focused push modes, but to your point BF3 and 4 handled the placement much better, allowing for more freedom. I always lean towards "square" maps over long rectangles type maps. I've been experimenting with the map editor in portal and there is a lot of unused space in the maps that Rush and Breakthrough could benefit from.
