The latest expansion pack has been released. Now, certain things are clear.

I just get bored playing "Heroes 5" after a few hours. I only play GSC maps, and they become monotonous. The artifacts are always the same (clover, ring of broken spirit, lion's collar, ...), and they removed the ability to find the Tear of Ascha. In general, in "Heroes 3," there was always hope for victory (even when you were far behind in development): you find some super artifact (and you don't even mind losing your entire army for it), and you're the king, but in "Heroes 5," there aren't any artifacts that I would be willing to sacrifice my army for. In general, I personally get tired of playing pretty quickly.
