I am thinking about some other blesses, but the thing about the E9W9 bless is that it helps both the sacred troops and the priests/kings. W9S9 would be my second choice probably, but the extra MR doesn't help the TKs at all since they already have 18 MR, and the priests could care less, though the protection from a stray arrow is useful. The main problem with the W9 bless as I see it is that it is a real PITA with the way quickness interacts with archers. By rights they should just shoot twice, but instead they decide to shoot, then run forward a bit, all the way to the front line.
Otherwise I would really look into a W9D? bless...
I hope I don't sound like I'm just shooting down everyone's ideas, I'm just trying to figure out the optimal playstyle for me.
