What innocent Garleans? Eorzea hasn't been attacking Garlean lands except for military bases often built on Eorzean land. If your part of an invading army you are by definition, not innocent.

However I agree it would be good to see moderate Garleans who haven't just switched sides. We have heard that there are factions in Garlemald and while Varis holds complete power and the public in Garlemald seems to currently support the expansionist agenda, it doesn't mean that there aren't groups who disagree with Garlemald's current approach.

Still, even if we do meet moderate Garleans in 4.0, I still expect Garlemald as a whole to be the main antagonist in the way Nidhogg currently is.
