I have no proof but I do not think Teutonic furry is applied in wars. In normal battles it shows up as a blessing. There are no blessings in wars. I have played Germans since last May and my troops definitely feel weaker in wars. Also there is a visual que when spawning your troops that does not show up in wars. In conclusion I am about 95% sure Teutonic fury is not helping us German players in war battles.
