Well not all of them, but some are.
Best example is the Barrage, this is the best formation i have ever seen and i dont even want to use it in my single-player games because considering my personal strategies this would be the perfect formation. Maybe.
Hard flanks is kinda similar, and the double-wall is much perfected wall formation.

No, i still do think TDM formations are great. And dark wing never seemed promising to me.

I'd just stick to TUrbine, i am already used to it.
