I did a forum search for "clutch" combined with a few derogatory terms before I posted this and didn't find anything. I just finished a couple of sets I had picked up and was greatly disappointed, and a little concerened, about a few pieces. Specifically:
The Shell Raiser Street Chase - the 1x2 yellow slopes and the 1x16 brick have almost zero clutch power. Before I had the upper layers complete, I could not keep this thing from falling apart. It just would not hold. The slopes just about fall off on their own. I have never seen this in a set before. But then:
Cragger's Command Ship - I don't know what you call them, but the little 1x1 domed pieces with the little black driving levers have EXACTLY zero clutch power. They fall off if you even touch them - the levers cannot be moved because the piece just falls off.
Both are new sets. I've never encountered this - I have a ton of sets. I think clutch has decreased somewhat, but combine this with the weird (I mean it looks COMPLETELY out of place for LEGO) hull piece for #70006
and it just made me feel a little concerned about LEGO.
I just noticed this hull appears in three other sets....
