Any system that enforces a cooldown on Eins and Zwei is necessary. I'd opt for a combination of what you suggested and what I did, where Zwei and Eins both share a 2 turn cooldown when one of them is used, but Drei is left alone. There's far too many scenarios where people can't break through one of the Geist Schritt variants, so opting to play defensively and fight back every other turn should at least be an option for someone who is unfortunate enough to fall into that category.
