while i like the look and feel I am afraid zerg will be afraid of this map. There are so many chokes and ramps that ff would scare me though i have my siegetanks everywhere on the plateau in front of my main.
i did not play the map obviously. but looking at the analyzer it really seems quite narrow.
there let me suggest one - probably major - change: make the two ramps to the nat/third plateau much wider and the path leading to the 'crossing ramps' a bit narrower. or even get rid of it.
could you post an image of a tank sieged up there?
