I just started collecting ML figures and so far I have Wolverine from the Hit Monkey series and Daken (Dark Wolverine) from the Arnim Zola series.

I really like the ML series, but I noticed a problem when making them stand back to back and comparing their height.
The problem is Daken is billed as 5'9 in height, while his father, Wolverine, is billed at 5'3.

But with their figures, Daken is just slightly taller than Wolverine. Sure, Wolverine's boots have pretty bulky heels, while Daken's have very flat ones, but that's still not enough after compensating for the boot's heels.
Sure he is shorter, but not short enough.

Are ALL ML figures not accurate height-wise or just Daken and Wolverine? If it's just those two, then which figure is the one that's out of scale height-wise?
