Think over that again.

The wizards would be making such a detailed plan out of necessity. What necessity? Humans attacking again. They made the plan not because complicated plans are better, but because it was the simplest one that had a long enough time reach (~600 years by your estimate, I believe) for the humans to chill out about the whole war. Any simpler plan would need to occur within their lifetimes.
