Revit Model Groups are a wonderful thing when you know how to use them and follow some basic rules. They allow capturing repetition in the building model, and provide a way to tag through the groups, maintaining unique instance properties of the contained elements for scheduling.
Some old rules no longer apply. I love the fact that Autodesk has been making strides in improving group functionality and stability from release to release. For instance, mirroring works very fairly reliably in Revit today (mostly), versus 2 years ago it was verboten… (although I wouldn’t recommend doing it… better to create left & right versions IMHO). I have four good rules to begin with that are hard and fast (until some new feature makes them obsolete one day).
