At this point here in the south of Germany not having DB would be an improvement.
Now it exists and you might even try to take it just to be delayed and disappointed. You'll lose your money and they behave in their arrogant manner with impunity.
Their customer "service" will definitely tell you how it's your own fault for having had the nerve to actually try to take their train. You might have even carried some dirt to the train for Christs sake!
So yeah. Not having it would already be an improvement. You'd just shrug and move on and take an alternative transport. Even horse and carriage would be better.
