General gameplay tactics and its features.

Friends, we enjoy the game... When I visit your forum, I hope to learn something new, not to nitpick over trivial details (like "I only play as Necropolis with this hero, help me...").
The difficulty should be less than max, and the map size should not be max for those who are just starting to learn this wonderful game.
