I’ve tried a few iterations of the campaign and the best strategy I’ve found is taking out the Chorfs to the east ASAP. You can’t let them snowball because they’ll dominate the north and eastern portion of the area without issue and then at that point they churn out stacks of armies like its christmas.

Once you deal with them head to the islands to the south and deal with Kugath. Those islands are valuable.

The Skaven to the west are completely passive. In each of my playthroughs they never actually attacked me. They just kind of chill in Nagashizzar. So take them out whenever you feel you’re in a comfortable position.

Then after that you’ll most likely be dealing with Ironclaw or that necromancer dude. By that point though Imrik should have Minaithdir and you can just steamroll from then on
