Where can we find more reliable statistics? The rating from vbn includes all the results from the seasonal games, for which players wanted to write reports. You can select from these reports based on various criteria, or you can limit yourself to the simplest: the number of victories for a hero/the number of games played with that hero. And compare for different heroes. For Castle and Valeska, by the way, this is the most reliable result, as there are the most games played with them.

You finally convinced me, you eloquent devil. I agree, Leadership and Ranged Attack are necessary even in the later stages of the game. Especially when taking control points, hives, ruins, and storming castles.
