I really like the idea, but it might also be rather an "altered melee" than a regular "melee" by the hiveworkshop standards.
While this isnt a review yet, the map currently isnt using th the latest patch data (can hopefuyll be enforced by setting game data to "melee (latest patch)"), which it definitely would need to in order to be considered "Melee". Also, the itemdrops seem to be completely over the top for a "melee" map.
