I'm a bit more irked at the price tag for 4 x of the exact same figure for a total of $100! This isn't 4 distinct sculpts. This is the phase 2 Clone Trooper with 4 x different paint jobs.
I can totally understand some of the confusion about the Shocktrooper, too. The Walmart exclusive Battlefront Shocktrooper just came out last year and was a complete PITA to get. It absolutely would have been nice to see it get reissued. But that character was a creation of the Battlefront game, and was an Imperial Stormtrooper with the red Shocktrooper markings like we saw in ROTS. And THIS Shocktrooper is a phase II Clone repaint. But the markings are so similar between the two that I can see the cause for some of the confusion.
