Walkthroughs for custom maps.

Based on the analysis – maybe someone here can help – http://heroesportal.net/tavern/?id=402827? ... And there, I saw that someone completed it in 15 days (I don't even want to imagine how).

Well, it says there:

I understand that in this phrase, the discussion wasn't about "Paragon" at all, and moreover, it was written even before version 2.0 of the map was released. As for the violation, it might be artificially increasing the number of turns to almost infinity using a bug with the Admiral's Hat (no, I won't tell you how, I don't use it myself, but this trick is known and prohibited in tournaments).
