Bad melee map unluckily. Here are the issues:
1- Let's talk about the terrain. Occasionally, I found some flatness such as in the starting locations. Then, the raisings and lowerings you applied were sometimes made badly. Let me guess, you used the noise tool in some places right? Well, the result is almost always terrible when you use it. It makes sharp-pointed raisings (like the ones I found) which look really unnatural. Next thing, I found that the snowy parts were only made of the "Snow" tile while it could've been better to add "Ice" and "Dark Ice". Tile variation man, tile variation!
2- Your items drops are the most exaggerated ones I've ever seen. There are too many damned Power Up items dropped from creeps. This is a melee map not an RPG so it is inappropriate to have too many Power Up drops. Things like Rune of Shielding, Rune of Rebirth and Rune of Greater Resurrection would ruin the balance and harmony of melee maps. But that's not all about your item drops. You've exaggerated with the chances of item drops. I saw some creeps which have chances of dropping 1 of various different items (e.g 20% to get this item, 20% to get that item etc...). The problem? They are of different levels. It's not good to find that once I may get a worthless level 1 item and another time a great level 5 one. Having a quick glance to the central red camp, I also noticed this issue. A level 6 charged item or a level 8 artifact. Dude, this is like the difference between sky and earth! A charged item of level 6 (the maximum level of its category) cannot be compared with a supreme level 8 artifact one!! And may I know why the creep guarding the bottom Goblin Merchant doesn't drop any item while the top one does?
3- Creep camps themselves are a disaster. How can you make a creep camp of total level 60 (yes, the ones in the center of the map)? They are insane to beat. Two 1900-HPed level 10 faceless ones deathbringer that can silence and animate dead + Two 1150-HPed faceless ones terror with sleep and mana shield + four damned 675-HPed faceless ones tricksters with that curse ability (and purge of course). They can cause all my army to have 33% to miss on attacks in few seconds. It was also disappointing to find out that some creep camps do not even drop items (like the one stated above). Look at the bandits camp. Nobody drops items in there. Another problem with that specific creep camp is that when I looked on the opposite side to find the equivalent creep camp, I found tuskarrs, not bandits. What was the surprise? The tuskarrs dropped an item. By doing so, the map is no more balanced. Another similar issue is the one of the Fountains of Health. 4 Unbroken Ragers vs 1 Faceless one Trickster + 2 Unbroken Darkhunters. Once again, you ruined the balance
4- This is a very minor issue nevertheless not to ignore. I don't think the Tavern is in a good position. It is too close to the starting location. Moving it to a greater distance would be better
My conclusion is that the map needs a lot polishing and refining. For that reason, the map is not ready for an approval. I will give it 2/5 and AWAIT UPDATE!
