Testing it now, will edit this post for the review.
Edit: The Review
Terrain 1/5
Sorry but I don't call that a terrain. If it would be something like wintermaul with paths and such, ok, but just a plain field of grass with a cliff in the middle?
Goal 3/5
Just the average: destroy the enemy castle.
Units 2/5
I have only seen 1 custom unit, and that was the water elemental that couldn't be killed (?) . All the descriptions were the standard ones.
Triggers 2/5
Just some teleport triggers near the barracks.
Overall 2/5
This map looks like it is the first version: The description isn't fully readable, there is no terrain except a cliff, you just start with some buildings, a hero and an unkillable water elemental. If you order them to attack the enemy, they will walk to the cliff and stop there. If you make them walk near the barracks, they get teleported to the enemy just like the units you train? This look really messy. My suggestions to make this a real map:
-Make a terrain
-Explain at the start of the map what has to be done
-If you really want that cliff, make a teleport portal with some nice special effect and let trained units run to that portal, instead of just instantly placing them on the other side of the cliff while the hero and the water elemental you start with can go there, too, by walking near the barracks
-Make custom descriptions: do not state that the taurens can be upgraded with pulverize if they can't
