I'm cool that they're deluxe class figures, but as we've discovered from Hasbro there are different sizes of deluxe class figures, and given the Throttlebots could originally fit in your pocket I simply feel ToyWorld's are unusual for being at the bigger end of the deluxe sizes.
While I would've liked FansProject's Stunitcons to be bigger (yeah, I know, "These are too big. They are too small."
), FP haven't downsized them in comparison to the rest of the Causality line.
Maybe the size of ToyWorld's figures are due in part to the engineering required (which, by the way, I love), but they just strike me as large. It wasn't a conscious decision on my part, it's the way it is.
I've ordered GrindRod, got Aurora on pre-order, and fully intend to get the rest. However, this is my opinion and I'm going to voice it.
