Well, I finished the map, twice. Once on easy mode with a beginner, and the second time on master and hardcore.
Conclusion: the map is very good. It has its own storyline, a large number of quests, and the opportunity to max out a hero (although scouting is useless here), and it has its own unique balance. Of course, it's a bit off, but it exists. The most difficult part was the last titan, but the difficulty wasn't that he was super-powered, but rather because of the artifacts, as he likes to give everyone the strength of a dragon, and you can't remove or steal it.
In short, I really liked the map; it's a shame that I didn't get enough points to reach legendary status, but it's still good.
