Personally I hate tricky downclimbing sections; I have no desire to have my training buggered up by movement that has no relevance to what I'm training for.
My local, Boulderwelt (Munich) is a repeat offender in this regard, and in general tends to set tricky circuits with complex, low percentage cruxes. This may well be great for entertaining folks for whom having fun on the plastic is an end in itself - the main market these days - but severely compromises their usefulness as an endurance training tool.
The UK walls I've been to this century - Works, Climbing Station, Highball in Norwich, Manchester Depot - tend to be better in this regard. The Depot really is the opposite end of the scale from Boulderwelt - completely cruxless monotonous stamina plods. Which is not a criticism, it's great for what they're there for.
