Theres no save game files, there are only game directories. The only way I have figured out how to "Quick save", is do your turn, save and exit the game. Then go into dominions 2 root directory, find the folder with the same name as your game, and copy that folder to another location. You can get away without exiting if you don't care about your orders for that turn. This is why I assume you were asking. Also, Alt-Tab switches to windowed mode. I have gotten in the habit lately of playing this way.

I am pretty sure the thread you mentioned is talking about human opponents. I have yet to see the AI attack with one seraph, and FH spam. I get numerous reports in my SP games that PD's have beaten an opposing army.

PD in MP games are a mixed bag. It really depends on the race your playing. Jotun for instance can get good results from PD. But no amount of PD will hold off an opposing player, or stop a strong AI. In MP PD is useful for stopping distance summon spells. For instance, Call of the Wind is an annoying but very easy to defend against. It will however always win vs 0 troops. A nominal PD is often enough to drive off the Birds. I haven't played nearly enough MP to give good advice, but just from my limited experience, as Vanheim, its not worth it to invest heavily in PD. Nominal investments however to ward off spells is a sound one, especially in key provences.

*edit*

Case in point, a PD of 2 or 3 chased off my flock of birds in my last turn.
