Very nice map indeed, played it quite extensively and I rate it a 9 out of 10 with a thumbs up.
The terrain is especially well made, I particularly like the terrain in the temple and the first zone. All of the hero abilities are quite interesting and work quite smoothly. Generally, the map runs very smoothly considering the amount of customization that you have done.
There's a very few quirks in the map, but nothing that severely subtracts from a smooth and fun experience.
- The escort quest in the barrens is a little bit wonky at times, the NPC has a tendency to stop and admire the scenery a bit too long.
- You can't attack your own, summoned creatures. While this initially doesn't sound like a problem, I have experienced twice getting a summoned unit stuck behind an obstacle. In the case of heroes with only one summonable unit (like the water mage or the hunter), this isn't a big issue as you can just summon again, even though you have to wait 90 seconds. With the necromancer, it can be a bit more of a nuisance, since when you summon a new undead, you replace the undead with lowest health. So even re-casting to summon a new undead wont get your undead unstuck since it hasn't suffered damage being stuck behind the obstacle (the system with automatically replacing the summoned undead with low health is superb though, really excellent and intuitive).
- It seems to me like the Chaotic Knight could use a bit of a power adjustment, he just seems fairly weak to me. I tried all of the classes in the map, both solo and with other players, and the Chaotic Knight is made to be a mix between a tank, a healer and a damage-dealer. Unfortunately, he doesn't do terribly well in any of the tasks. I know it is very tricky balancing multi-purpose heroes, but I think that the Chaotic Knight could do with a little adjustment.
Other than that, the map is really good, extremely professional and entertaining.
Edit: Just noticed two additional, minor things. Again, this doesn't detract from my rating of the map, it is very excellent.
- The icon for the Rogue's Vanish ability is the Windwalk icon (I figured it should be the Vanish icon, since all other abilities that provide a buff use the same icon as the buff).
- Minor spelling error in the Ice Lance ability (Conevrts instead of Converts)
- An option to "sell all" would be really neat, sometimes I had several screens full of gear to sell, taking quite a substantial amount of time.
