Vic, you'll even say you're ready to prove in a series of games in Sode Maretti that Necropolis is better than Castle on Jebel :D
Moreover, the experience of tournaments like "Shakti vs. Gunnar" shows that a series of games doesn't prove much. Well, Gunnar won then, who did that convince of what?
Studying the balance of factions needs to be done differently - a tournament is created, such as "Castle vs. Necropolis on Jebel," and in each round, the colors are specified, for example, in the 1st round, red Castle vs. blue Necropolis, in the 2nd round, the opposite, and so on. Opponents switch colors (and accordingly, factions) after each restart. This is to compare the factions themselves, and not the skill of their players. Then, based on the results of several dozen games and player surveys, it will be possible to draw more or less adequate conclusions.
