Tactics and strategy in Heroes of Might and Magic V.

I think this will be a shocking revelation for the masters...

Of course not, but something will definitely be new... Plus, they will correct me... It will also be useful for beginners, but a little difficult...

P.S. I've seen many "masters" who consider themselves the "fathers" of Heroes...
But in reality, they don't really know how to do anything... Do you, for example, consider yourself a master?
