1. A pirated version equals a ton of bugs. Also, there are no dynasties. It's surprising how people could play as Inferno if there are no Inferno heroes in the list of basic heroes, and it's impossible to create them in a pirated version. 2. Indeed, the stat increases for dueling heroes are very slow, not +3, +4, as someone mentioned, but less than a hero could gain by developing on the map. 3. It's likely that the demons had a lot of luck, which is why the enemy hero was able to open the gate twice in one round. I didn't understand the part about restoring 20 Destroyers.
