"Melee" refers to unalteremed maps as they are played on the battlenet ladder. This seems more like an "altered melee".
I'm changing the tags so that it can be seen (and reviewed) by those who are interested in such maps.

Resources in Use by Dalaran Defense v2.0 | HIVE
Please credit these in the description. Any custom model used must be properly credited.

1. Murloc unit name is missing.
2. Is Cannon Tower being Beast Breeding's Requirement intentional?
3. Same goes for Nerubian Tower for Crypt upgrade
4. The Infernal Knight can use some unique model like Direfury's Black Knight for example.
5. Crypt Rider has mana, but no spell?
6. Sylvanas for both human and undead? What?
7. Fountain of Health's name is ...

As a defense map, it falls flat in the term of unique units given. Most of the units are just the default ones. Hero can also use unique spells than using the defaults.

As it stands, this needs some serious improvements.

AWAITING UPDATE

Still no update or any activity from the author.
Also, is this an update of your already uploaded Dalaran Defense map, or the other way around?
Either way, moved to Substandard until updated.
