As an addition, keep in mind the viability of dominion victories: you have stacks of high-stealth H2 priests. to use I won a MP game once with a N4E4A4 Dom9 gorgon; I believe my scales were Turmoil 3 Sloth 2 Growth 3 Luck 2 Drain 2. I got into a pair of protracted mid-game wars with two nations (Ermor, Caelum) in far more magically-powerful positions, and they both went like this:

Fight holding actions with Maenads and various Centaurs to slow down their armies. Use Cloud Trapeze to drop the gorgon on really powerful armies, slaughtering them mercilessly. Meanwhile, sneak 2 dryads into every single enemy province and start preaching like mad. Eventually, they will throw in the towel in frustration with the gorgon, or get dom-killed.

Most of the time, I think my gorgon was kitted out with Rainbow Armor, Weightless Tower Shield or Shield of Valor, Frost Brand, Birch Boots, Amulent of Antimagic, and Amulet of Revig or Pendant of Luck. High dominion and sporadic control of Gift of Health gave her enough HP, and her MR was ~32 in dominion (don't forget Iron Will!), so my only real fears were Drain Life/L4L spam and Gifts from Heaven.
