Ack! You are right about the gold & blond hair combo. I really would love to chat with the designers. And it would be interesting to hear about what their design process is and understand what is driving some of the decisions they make. Oh and I'd love to give them some small suggestions...just a few 
What designers?
On a serious note, you really have to WONDER if they actually think about things. On that jungle "hovercraft", the guy with the holster doesn't settle in the boat. The samurai from the mag has that issue with the neckpiece versus hat. Then there's the invisible magical arrows from that "Diana" fairy... And this is just a couple of things from the top of my (poor old) head! And not even getting into weird colors..
I like the idea of a theme - and putting a little more thought into how they might be recombined. And you are right about the different bodies that are compatable. All the body parts should be compatable within the figures series (and have no holes) since they market switching to parts around.
Exactly. I'm still not over the arms mess. I don't think I will EVER get over it

I mean, the figures series as they are work well for those of us that are into every theme AND have a bunch of parts anyways, that allow us to not only fix what they did

, but also move around the parts as it was (supposedly) intended...
What's a buyer that gets half a dozen random bags supposed to do!?
