I found the following reasons for this map to be rejected.
- No originality nor creativity nor unique. It's just an exact DotA clone, with altered heroes and plenty of imports. He most likely to have used the DotA Template map as a base.
- Map submitter has not put a proper credit list for all the custom resources he used. Not even in the map itself.
- Most of the custom heroes have the exact same abilities as the original heroes. Only the ability names have been edited.
- The description is a lacking quality and could be made better.
