I have tested this map 1v1 against the computer today.
Gnoll-Tal is a two man warcraft melee map. Your goal is to take one of the four races and defeat your opponent.
I can't say much about this melee, beside that it was done good. It is symmetrical, thus properly balanced. The terrain was done in a good manner, the ground tile variation was good, the dodoad usage aswell. Enough trees were placed. However I didn't like the usage of the Blizzard cliffs and the rocks on them, it looked unnatural and odd, you should avoid those. The drops were done fine, however I found some "problems": The creeps guarding the Goblin workshop dropped a tome and a item. However both the tome and the item were dropped from the same creep, it would be good to separate those two. The gameplay was good, you placed a tavern in the middle, avoiding the fountains, what I personally prefer. You should fix the description of the map since the "Melee map" isn't good, you should copy the story you put under it.
To conclude, this melee was pulled out quite nicely. For now I will put 3/5 (Useful) and Approved! Good job! It is leaning to a even better rating, once even better terrain and drops are placed.
Note: The description ingame, you have under the map is copied from Booty Bay, why? Fix that.
