On inwarcraft.de, in the past month, we have collected some suggestions that would improve wc3 mapmaking. The requirements were that backwards compatibility should be maintained and that it should not stray too far away of the existing engine. The results were posted in blizzards suggestion forum now, although we do not expect much out of it. While I won't add new wishes or remove points, you are invited to discuss the detail or contribute to the next round. Despite being named inWarcraft's Wish List at the moment, we would actually like your cooperation in the matter. We just wanted to present this as a product of a community but not pretend it was of the whole wc3 world since it was not until now. The thread is found here.
