Which class’s ultimate ability do you like the most?

I voted for the Mages. Yes, it's difficult to obtain, and it requires sacrifices. But the correct and timely use of various spells in battle with large armies (especially, of course, if the opponent has more monsters but is a simple Barbarian with 27-2-0-0 stats) is the most interesting aspect of the game. And the difficulties and sacrifices associated with other abilities (minus ranged attack :( ) make it even more interesting.
