Which Nations Are Best for Turtling?

[Quitti]

In single player it might be so (referring to ma ulm here), but overall researching up a few evocations that decimate PD or simply getting indep crossbowmen in sufficient quantities isn't a problem in MP. Also, sc's are quite capable PD clearing forces in themselves (which is kind of their point - to destroy chaff or other sc/thugs efficiently enough). Still, Ulm has solid troops that can guard against most out of the combat unit summons unless they are really massed per province.
