What do you guys think about those huge specialized Bionicle pieces like Gadunka's head, the Visorak torso, and even things like Mata torsos, among others?
Personally, I've never liked them at all. They're difficult to MOC with and don't provide much of a interesting build with all of that bulk. I've seen some people use things like Metru torsos as legs and such, but they still take up so much space and are difficult to build around and modify.
What are the most creative ways you guys have used these pieces in MOCs, and what are your general thoughts on them?
