well, yes and no

they actually talked about this on the forums

basically, Pantsu-nugeru-mon had surprisingly good framework when they opened him up, and had good 'bones' for the stuff they wanted to be able to move (it's likely the same for Dr. Mundo and Alistar, among others)

Eve on the other hand does not have good bones... iirc, the biggest problem is her tassel things, which only have 5 in them, while later designs with similar things have many many more...
