It's meant to be playable terrain, not just terrain so what do you expect? The project was dropped too. How about you try starting a map that resembles WoW's northrend map.
In a very fun way I recommend playing version 1.11 not 1.12. The idea is kinda like chess... Each race has special buildings that help it to own the others... Castle fight is like melee, but automatic, and the actuall units you have spawned are a lot more important, not how you control them.
Ghan has said he has fixed this. Monovertex please confirm this fix. This was only a problem with people that had signatures in the upper levels like not the special members but the respected members.
