Legions are great. I love the little guys. However, we very, very rarely get a Legion with both elbows AND knees (Warpath and Cliffjumper are the only two who spring to mind). While the decision is usually made by sculpt or design (and sometimes they're both omitted), which do you think is more crucial to the figure? Personally, I prefer elbows. With knees, it's tough to utilize them and still let the figure keep a standing pose. And with all the Legions being able to hold guns, being able to wield them has gotten a lot more important.
