Question: Defense Dilemma

[Esben Mose Hansen]

You generally have 5 options:

1) Blanket the area with armies, each large enough that local defence+army will be enough to defeat
2) Use traps or guessing methods to predict the next move and squash his army with your biggie.
3) Spam the you provinces with castles
4) Use a magical attack spell to jump the defence (the ghost spell seems effective for this)
5) Counterattack, devasting the oponents provinces just as he devastes yours.

Playing catchup is almost never worthwhile.
