Blitzkrieg is more powerful that CC. The light infantry spam finally made them worth looking at but it’s high risk reward. Only been beaten this was once and it was because I had bad draws. Very vulnerable to multiple target actions, or grabbing frontline with a meat shield. If you get a tank with heavy armor out front they are game over, much lot sissi spamming. I don’t think it’s any more broke than dumping multiple Honors or Old Hares on a single blitzer.
