Having written a 100+ pages paper in passive voice in German whose writing style my supervisor called "very elegant and readable", I'm not sure it's the construction using auxiliary verbs. German is very similar when it comes to passive constructions but for some arcane reason in English passive voice doesn't sound as good or natural. (Not that passive voice is natural in German – it isn't. But it still sounds orders of magnitude better than in English.)
