There are no bad maps. Every author puts in effort and spends time, which is already a good thing. Some maps are interesting to play, while others are boring. Since I mostly play against the computer these days, this map is boring to me. It's boring because, due to the lack of strong garrisoned gates or simply strong monsters at the junctions, it's impossible to develop properly. The opponents just run around like crazy, and the game turns into a chase-and-kill scenario. Personally, the last time I played it, I limited the number of heroes to two per faction. Otherwise, it's not enjoyable. That's how it is.
I recommend playing as the blue or green player, or even the yellow player. I wouldn't recommend playing as the red player because, in terms of design, its territory isn't very appealing.
