Why such strict rules? I do believe it would be better if we could use the ultimate terraining map (a resource that is free for all to download), and post our bloody pictures on the forums. Honestly, something tells me you have never hosted or participated in a terrain contest before.
Dude. It's just the way it is. Besides, this is to test how well we can do when we're limited to less resources. Now stop complaining. Rules are rules.
