Impressions of Heroes V, for those who have played it.

Why do people say that the ultimate ability is unattainable? For example, today I completed the single-player map "Island for One" and received the Necromancer ability "Scream of Terror" at level 29. There were no problems. You just need to level up correctly, and that's it. As for TIGRENOK... I think he either doesn't have the game or he plays it not at home, but in an internet cafe. He wants to play more, but doesn't have the opportunity.
