Introduction of Haven in the Stronghold vs. Dungeon tournaments.

For a friend like Caliban, those who value their time don't play Heroes 3.

That's not true. Those who consider Heroes a waste of time simply don't play it. That's a much more accurate statement. And this, in turn, again supports the MANDATORY use of Overlord's Hut (OH) in TOURNAMENTS. If you want to play without OH, play fun games with those for whom it's also acceptable.
