Discussion about the Stronghold faction.

I don't understand one thing - why divide the goblins into single units and a main stack?

The main advantage of the trap is not dealing damage, but slowing down the enemy. And for this, even 1 goblin is enough. Besides, it's better to place traps constantly, and if there is only one stack, then due to the cooldown, you will only be able to do it once every three rounds. Traps allow you to:
1) keep the enemy away from other troops;
2) help avoid focusing your troops and, conversely, help to pick out single enemy stacks.

But this is with the Dynasty weapon.

Exactly:)
