[Warhammer]

Do not underestimate the W5E. They are one of the few units that get better as the game goes on. You have the mage power to make them immune to everything! You can have the mages to give them Legions of Steel, Strength of Giants (don't really need it, but it helps), fire ward, thunder ward, etc.

The water bless is also synergistic with several of your pretender options. I would save the points on the water bless and put it into dominion to get more of the W5E.

Your two questions should be:

1) Should I have another major bless?

2) What scales should I take?

Note on the scales, you don't NEED great scales. You can take sloth or turmoil. The only scale I can't justify with TC is death. Even drain, I can at least justify if I need points (you've got great cap researchers and can forge quills and lanterns).
