Managing 8 heroes on the map.

“Paid” dungeons – in some ways, this is a good idea to prevent excessively large imbalances caused by someone acquiring a valuable hero for free. The main thing is how this is implemented. Personally, I am in favor of either having guards at the dungeon or offering a “release on bail.” This is logical: both the Necropolis and the Inferno have guards, but the dungeon is unguarded – anyone can just walk in! :) And an additional hero is usually more valuable than a pile of gold!
