HA! I agree with them hating us customizers... or perhaps it's that they know they can make crappy figures that we will buy 4 of just to make one custom figure?!
Your right about the hip joints looking a little funky and definately are not aesthetic. Some of the newer ROC figs seem to be a little better though I think.
I've been able to get around the aesthetics of the ball joints by adding belts with holsters, pouches and dangly bits to break up the recessed area around each hip. That seems to help a little bit.
It's all a give and take with action figures though, sacrifice accuracy and aesthetics for articulation or vice versa? it's a hard choice sometimes. Thats where we as the customizer get to make the decision on how to tackle these problems and find a nice blend of both... or try at least!
(btw I hoped that you didn't take my comments personal, I was in a rather bad mood eirlier and thought my comment might have come off a little snappy... of course that's me trying to be politically correct and worrying too much I think!)
