Watchtowers, or course. A well scripted mage squad worth 1000 golds will wipe
out the floor with any PD, including insane ones. It will wipe the floor with
any known well-scripted mage squad, as well.
Forewarned is Fourarmed, right?
For me the whole PD discussion is silly. I do not want PD that can stop a
determinate turn 30 attack. I do not want my temples and resources to be
wiped out by an attack I cannot defend against. I like the risk, challenge
and mystery involved into storming a castle without a way of knowing what I
will encounter. I like being able to tailor a reaction squad against the
invaders. I like thumbling my nose at whatever artilery spells the enemy
throws at my besiegers. I like throwing spells at besiegers.
I think that invading and storming on the next turn is as damn close to
perfect as it gets.
I would still love to be able to forge a 160/160 earth/astral item that
would act as a portable dome. I believe this is close to impossible to
program into the existing engine, but imagine the possibilities!
