As a general rule of policy and opinion, I dislike these style of maps. The whole spawning style of gameplay encourages players to just sit back and mass up units till they feel they have enough. Basically, there's no real incentive to create action. With that said, I'm going to look at what you've done.
What you have done, in my general rule of policy and opinion, is rather nice indeed. You have proven you don't need lots and lots of imports to make a good map, you have some interesting abilities (I like the Precision ability! How'd you do that one? I love it!) and have created a nice terrain to play on.
Unfortunately, there are a few mishaps. For example, the Spider Pass building has Slow, which costs 50 mana. The building has no mana

. Shame, really. On the plus side, your tooltips are really, really awesome! They give each unit a feeling of professionalism (if, indeed, that is a real word. Even if it isn't, I hope you still get the point

) and makes the player feel very comfortable about reading the tooltips. To me, it really ruins a map when someone decides to make awkward tooltips such as 'This unit could be called imba xD' or 'Players will call you a faggot for getting this'. Nice job in that department!
Well, for me, there's only the gameplay factor that stops me from wanting to play this map (sorry, but spawning RTSes are really sucky to me! At least you know why

). I think that if you were to go on to include more imports to get an overall better look (like some new models for the Goblins

. The Ghoul can work, but requires a very open mind and a lot of imagination to fully accept it

). Overall, nice job, and I definitely reccomend this map to any who like the spawning style RTSes. I give this 3.5/5, as I do reccomend it, but it's still somewhat borderline useful.
If you do go on to recreate this map, perhaps (and this is just a suggestion) you could create a wider variety of units and make it so that players have to research different units in order to start spawning them. Just an idea, but perhaps worth a look? Anyway, good job!
