Is it really surprising though, when there's like more Warriors of Light than normal people in the land? I wouldn't invade that shit either. It's like invading a town where every other person is a super hero(mind you I'm sure this happened in comics).
Should have been smart and invaded during the Tanaka 1.0 era
Had all the time in the world with a defenseless Eorzea devoid of life instead they just lobbed idle threats while we were in Thantalan.
Oh well.
