So what would you suggest we do? Lock the War Island at absolute parity in noble count? Prevent it from starting if there aren't absolutely equal noble counts in all 3 realms, and declare it over as soon as one realm has an advantage over the other two, because of course they won't be able to win now that it has more nobles!
Strategy is meaningless.
Leadership has no influence whatsoever.
The only factor that affects your chances of winning on the War Island is noble count.
Right?
