- What are the drawbacks of Heroes 3? (What didn't you like about it?)

I don't like it when a secondary Sorceress or Eagle Eye is offered to a hero :(

but a secondary hero with the Sorceress skill can be quite useful: being able to transfer spells from one hero to another on some maps will be very important, for example:
on a map, one hero receives from a scholar on the map or from a Pandora's Box: Resurrection, Town Portal, and other such spells of levels 3-4, then the hero-sorceress transfers these spells from that hero to the other heroes we play with.
