Don't know what people are talking about. He clearly said that it's an attempt at terrain. It's completely obvious that he's not done with the terrain and thus should not be concerned about making builds and stuff. Mainly talking to Fred here.
Regarding the terrain. I think it's one of the most original and daring pieces I've ever seen. People, most of the cases, refrain from making sharp terrain and have no idea what they're doing. All this could need is maybe a slight variation and color shift. But nothing too drastically. Love it. Especially as a seacliff.
Don't think you can use it as an "overland" TDM as it would be too much jumping. Or else you would have to redo the terrain alot. However, could do well in a dogfight.
