Dominion Vs Military

Sure your troops get +1 moral and your Pretender is beefier, but you can't win the game with only your pretender...

Dominion does more than just give you a +1 morale bonus and more hit points.
Think of Dominion as giving yourself "home field advantage" and every battle as a play-off game.
Would you rather fight under your Magic3 scale or your opponents Drain3. Do you want your Heat2/3 or that cold2/3 scale and all the disadvantages that come with it ?

If you don't worry about pushing your Dominion that means you'll have to fight every new battle "on the road" once you have reached your dominion borders and want to continue expanding.
