Well, they have superior technology, a bigger army (even with the Milita in it the gallian military was outnumbered) and Damon seemed to be in charge of the defense. I also question Maximilians ability to make rational decisions.Just beat the main game. Felt good. Also did the Edy Detachment mission and was kind of disappointed since I was expected more than just one mission. Some great expansion on the characters, though I never unlocked Lynn for some reason in the main game so she took me by surprise.
Started Behind her Blue Flame and finished the first battle but goddamn are Imperials incompetent. How the hell did they get so far into Gallia? Selvaria must have literally fought in every batttle for them to reach so far.
I played my way from the beginning, never encountered problems. You can play a skirmish or two to cope for the loss of Exp and DCT, or just go in with what you have. If you force yourself to just use the one tactic, you might have missing out on the fun part of the game.Rating gives you mad EXP though. Faster grinding = faster you can then play the way you want.
