The second half of the army refers to the heroes. Dungeon is strong against Haven because it cannot be affected by magic. Regarding statistics, the more outcomes there are, the more realistic the picture of "strength" will be, because approximately the same number of strong players will have played for a specific faction, and so on. This will have less influence, and the true differences between the factions will come to the forefront. And if in 180 out of 200 cases, Life loses/wins against Haven, would you say that this is a coincidence?
