Wasteland king what's the best way to defend your hub?

You will want to choose the 5 strongest players in your state to captain the 4 towers with the most strongest captaining the hub. This answer can get complicated based on your knowledge level, so I will answer assuming you are a newer player.

Stats & rally size are the most important. Ideally, captains should have large rally sizes AND strong stats. When choosing captains, forget might rankings as weaker players can gain a lot of might from having a lot of troops. You need to look at their actual strength.

Once you have that figured out, you can then assign players to fill in the hub and towers. This is where troop tier comes in. Put the highest tiers in the hub (i.e. T11’s, then t10 if you don’t have enough t11)

Captains super reinforce which will apply their personal stats to those that inhabit the building, which is why tier level has some importance.
