This is an interesting topic. I have seen a couple of really nice BTB maps on the top of the large forge island. I have tried to make a BTB map using nothing but rocks and found it too flat and too open (sandtrap-esq sort of map). As for elevation, I think there are plenty of objects, including large rock objects, to forge with. For dominion, the issues you raise of long sight lines and lack of elevation are definitely a challenge I would not mind at all. One thing I would experiment with more are trees for soft cover. They seem to have a very interesting use.

The problem with Ravine is the palette - it has only UNSC structures, when the canvas is clearly a forerunner theme. The only forerunner object in the entire palette is the Artifact. The problem with Erosion is that the canvas has no where to build a decent flat surface of natural terrain. Any flat surface will be perfectly flat blocks. Impact is the best. And I saw one great map thus far on it, Breach, by BlaqCloud. It is a missile silo theme and it plays well for a first iteration forge work. Impact is the only canvas whose palette matches the theme of the canvas and has a large area (off terrain) to build in. But if you want terrain maps from Impact, good luck...
