After lots of looking through lots of crappy figs (which I happen to have in abundance), i came across two in particular.. The ROTS ATTE driver and the 501st Tactical Operations Trooper.
Both pioneering figs that come with removable helmets... and ball jointed hips.... (and the worst articulation below the knee and crappy twisty elbows that the arms slip out of) and in my opinion are two of the worst over all figs that i ever hope to see.
I dont even know how many of these I bought Cardedin stores and online at release time and kept all minty, until I opened one for my son just over a year ago and found out they were the worst ever.
I still have them... and keep them only for the nice little fig stands they came with. and maybe as fodder .... and sacrifices....
