Regarding expansion with combat pretenders:

Don't neglect protection! IMO prot 12 is by far not enough, especially if you haven't got a decent shield.
All your fear, awe and even petrification of the Gorgon (a great SC pretender!) will help you nothing against a good bunch of ranged units.
As MA Man I met a Wyrm as well as a Prince of Death early in the game with a medium sized army of Longbowmen (~30).
The Wyrm barely escaped due to his high HP, the PoD due to flying. They both didn't stand a chance.
So prepare for ranged units. High protection is the easiest. If you don't have it you should have ethearelness, mistform, air shield or something the like.
