The case assortments have been bothering me since last year. For the 2008 assortments, the case ratios were pretty good. You had some with duplicates of the army builders, others with duplicates of the new figures plus older figures, and others with only new figures.
I think the 2009 wave with the green Clone and Jar-Jar was the first case that really bothered me. You only got one of each new figure, and eight older figures. A couple of cases for the red card series really got me irritated, as there were duplicates of Echo and Greivous, but not the new ARF troopers.
I would be much more inclined to order cases if there were less older figures. I think including duplicates of each new figure and filling out the remaining spaces with repacks would be a good way to go, especially if the repacked figures were troopers.
