From what I've heard of the suggested distribution scheme, it's really, really problematic: not only will there be cases of the random boosters (so, one of each of the fixed figures), but the individual boosters will have their own SKU #s: One for the trolls, one for the ogres, etc. You can buy a case of Troll boosters (each has a troll + four randoms).
Working out the numbers of the eight or nine SKUs this creates? Total and absolute nightmare for Wizards, distributors and retailers. This could go badly wrong.
