Tactics against Necromancers.

I checked the save files, thanks for the link. The game differs significantly between 200% and 100% difficulty, and I'll have to relearn how to play, as I'm used to playing on 200%.

Usually, people play on Queen difficulty (160%)!
No one plays on King difficulty (200%) because it makes the game too long, and much depends on the map. For example, if you don't find a certain resource, you'll fall behind in development...
Some players use Rook difficulty (130%) to ensure the fastest possible start and accelerate the game!
No one plays on Knight difficulty (100%) or Pawn difficulty (80%) because of the inadequate behavior of the neutrals.
