Just to clarify I'm not suggesting all figures should be in scale. But if you look at the size difference between Deluxe and Voyager it is reasonable - certainly enough to show size difference without it being like David & Goliath. However, Leaders (certainly in the movie lines) dwarf every other size. The difference between Voyager and Leader is immense. If you bought Leader Sentinel Prime and Voyager Optimus Prime they don't look even reasonably as though they could stand side by side. On the other hand Voyager Megs and Deluxe Starscream looks acceptable. So the question is would you prefer Leader Class toys to be smaller than they currently are to make the Deluxe>Voyager>Leader size difference more of a step by step increase?
