I think in Dominions just base scortched earth doesn't work that well. You need to implement other things to it which aren't exactly true to its real life counterpart - such as raiding the enemy's lands and burning HIS temples, HIS labs, HIS fortresses down, while pillaging, taxing 200% and so forth if he does not follow, in effect forcing him to follow instead of invading your heartlands which might be in crazed troop building phase (reanimating ghouls as Lanka is a good enough excuse to kill off your home province IMO, not to mention having 200% tax with patrollers to maximize your own income).

Doing anything you can to postpone the inevitable is... Well, encouraged by the way this game is played, just the way you do it depends so much on the playstyle of your opponent. Defending your lands against much more powerful nations (and crazy aggressive players) is pointless when you can do much more damage in the enemy's lands with relative ease, for instance.
