"6. Maybe a levelsize similar to BBSwing might be ideal."

I haven't really attempted making a duel-sized battle level yet although I probably will sometime. So I just think along that size might be good.
Battle1 is bigger but has very certain hotspots (for one instance take the Seek PU area and near below). Therefore making a lot of the other areas rather worthless which I don't like. But I don't want that kind of level.

Oh and just another thing I felt I need to clear up, is that you don't have to let me betatest your map. You can get others to test it instead if you like.
