Heroes 6 - Discussion

Necropolis! Necropolis! ...I'm not a gaming expert (I only played the third and fourth Heroes games a few years ago), but I've read a lot of topics and posts on the forum, and why is Necropolis considered the best everywhere? Or was it just a coincidence for the developers? Or is someone among them preaching a cult of death? Or are the majority of forum participants close to them in spirit? I thought that all factions were initially equally balanced (perhaps the game was designed that way? Otherwise, I'll either have to throw the game away or become a goth), and then each player chooses and plays with a faction that is close to their worldview.
Chingis, if there was a choice, I only played with the Haven faction on maps and successfully completed Broken Alliance and others.
