I occasionally watch for a few minutes. The games themselves make it clear why csarmi said everyone ends up with 8 heroes very quickly, why Expert difficulty is not a problem, why Necropolis is imbalanced, and so on. The maps are so rich with both neutrals and resources that these are only natural. Downsides are the East European playerbase makes it hard to follow the chat (since I don't speak any of the languages), and boy do turns take a long time.
If anyone are familiar with these games I'd be curious about details of the competitive scene
