Yeah, good point on the "Lords of Byston Well" figures...I'm disappoint by that aspect of them! Great concept with the good sculpts and planned articulation but the loose joints are a big minus for me.
Mine's head is fine, but he can't hold his weapon in his hand over the horizontal plane or it slowly falls back down. Sometimes ball joints seem fine, but other times whole runs of figures can be loose in various places because of them (maybe its the way they're being produced?). I do love them for head articulation though.
