The best PD ?

[Baalz]

Suaromatia and LA TC have very solid PD with a mix of good archers and heavy cavalry. EA Aby is good, but since each point of PD gets you a single guy they really only shine one you get critical mass putting them not that far ahead (IMO) of nations who's PD really rocks at 20+ (ie. Mictlan). EA Aby PD of 10 is fairly meh.

I know its standard routine to bash monkey PD, but I find they work pretty decently in some conditions because of their large numbers, good defense, and lots of projectiles. Likewise, Caelum can be effective under some conditions because they fly forward to attack turn one. Neither of these are nearly as awful as Fomoria (my personal pick for worst PD) or Machaka.

Best PD?

The standard answer would be "depends on the circumstances". There are some PD that suck without mage or priest backup due to having low morale or subaverage equipment trying, but failing, to compensate with numbers that turn moderately awesome with just a bit of backup to keep them in the fight or buff them.

LA's Bogarus' PD, the scum of the scum, is an example of this. There are just so many members of the PD (IIRC you get 3 medium infantry, 1 heavy infantry, and 1 archer in total per point over 20) and Bogarus strength lies in its exceptional mages, so you can perform amazing PD+mage defences if you have the money to plop down in a strategic location... but at the same time it is poor everywhere else and the low morale archers break for a bad word, so...

If looking at PD without any sort of backup and PD that is both nice before and after 20 is reached, then the heavily armoured human nations are probably the "best". Nations such as Ermor, Man, and T'ien Ch'i.

Is there any list of updated PDs for all nations?
