The specialist box is mentioned in the blog above, basically similar to the 'soldiers' box but with heavier armour so you can build thinks like knights and man-at-arms.
I get what you mean on the proportions, I think it's because they're more 'natural' sized in things like hands and heads than say GW plastics, and they're closer to a true 28mm scale.
I still like them, but I'd probably not mix and match them from different ranges, unlike my earlier warband (although they supposedly work with the Fireforge range).
All that has to wait till I get my new glasses though - really can't see close up any more (yep, old enough to need varifocals
).
