Until they go to war and get slaughtered with that strategy.
Or until the KD gets big enough that it runs into organized KD who just has a decent thief to do a few CBs and give the attackers super easy hits.
Or until the human A/ts eat them for lunch...

At the very worst, OMAC could just make Watch Towers only work against sabotage operations and TDs only increase a provinces OFFENSIVE TPA...
