Which school of magic do you prefer and why?

Judging by your previous post, you're playing random maps in the campaign. That's not very interesting; there's always an easy way to win. Try playing at least the standard difficulty, and the resource situation will become much worse, not to mention player-created maps. There are no "Gutalinas" in Heroes, but "Conservatories of Griffons" do appear, albeit rarely. And how do you determine the number of griffons inside? Save-loading? Come on, that's not fair. And, by the way, I didn't say that "if the hero is Solmyr, there won't be any money problems," there will be, of course. If a hero specializes in something, they should use it in as many situations as possible.
