There is no main quest in ap at all :p you can do whatever order. For begginer it might be hard indeed but if you got familair with game it wont. Personally i played on imposssible difficutly and i decided that after rusty i did not go to Verona, would be too easy. I went to Nameless ^^ 3 times harder than Verona xD.Enemies armies wiere 15-20 times larger than mine but stil i could win :>
With just one unit, not 5. And cleraed all. Even few fights without any unit lost
