I replayed Edy's Detachment today and came up with a solid strategy that got me an A rank, with a ton of extra CP to waste on the 4th turn. I did have to reload a couple of times because stupid Susie went all pacifist on me...

Yeah the bummer is that Jann becomes largely useless after all the tanks are gone. Lynn is an absolutely awesome base defender though...
Have Lynn (and Edy if she's still in the base), face South and make sure your rifle users, Susie and Homer face north. Since Susie and Homer wont jam people from the South, they'll get in range of the ShockT's and it's game over for them.
Also played through the Selvaria mission pack,
(both branches) overall the mission pack is great fun, and it was refreshing to see the other side of Selvaria. The only thing that felt weird about it, was that as far as weaponry goes, it felt as though even though I am playing as this mighty Empire. My weaponry was still vastly inferior to the small Gallian nation, IIRC this is partly explain in the supplements of the story though.
Gave Vyse the Ruhm, getting ready to prepare myself for EX Skirmishes... also playing as Valkyrur Selvaria fuckin' rocks!
Oh yeah, also they patched the game to 1.20 before they released the DLC to add the Extras option to the menu, but I keep hearing that they lowered the health of certain enemies as well... /shrug
