Troops vs magic, what am I doing wrong?

I've been playing a 300 everything EA game on Faerun map, and not a turn had passed without AI wiping a 125 PD of mine here or there. Everyone from Sauromatia to Atlantis to Arcoscephale to the japanese. Not with particularly large armies even, typically in 500-1000 range, and that's with normal difficulty.

Of course, I played Niefels, and their PD is notoriously sucky, or so I've heard.
