Wind of Change

I think the changes to the game mechanics have significantly altered the gameplay, and in my opinion, they have increased the chances of weaker players defeating stronger ones.

Yes, the mirror map has appeared, but it hasn't made things more balanced. As Wiss wrote, having a Necropolis player or leveling up a hero (Earth, to be more specific) is still advantageous, but it has reduced the element of surprise in the map. There don't seem to be any simple answers.
