I'd say no, and for three reasons.
The first is that I buy duplicates of several figures, especially Cobra characters and troops, and the extra cost of the cases would be a total waste of money.
Second is that I can get cases from
MDM Sports myself for the figures I do keep carded. I believe they're currently on backorder, but I just got a shipment of them last month.
The third is that I don't believe Hasbro's "official" cases are actually manufactured by ProTech Products, Inc. Even if they are, the cases branded as ProTech are more sturdy than the ones Hasbro sells with a
STAR WARS logo on the back, and I enthusiastically prefer them.
