I’ve seen several un-boxings now,
I’ve noticed a trend of pattern, and it all goes back to how the box was packed. If you have the two sheets of roundels, Set up Cards etc on top of your storage boxes then generally they come out fine (Mainly I am guessing due to the two sheets acting to disperse any pressure on the boxes. However if you open the box and all you have is the spacers (which are horrible) on top of the boxes with the rule book and money, chances are the spacers will have caused the creases as they will have buckled under some kind of foreign weight being introduced onto your box during shipping.
That being said, I suspect this is a combination of manufacturer error in the packing process as well as in shipment, the boxes were obviously stacked or placed into some situation where stuff was placed atop them and despite being double boxed, the weight of the foreign objects was enough to cause the spacers to cause the damage.
As for broken pieces or warped boards, more than likely those are cases of quality error as, let’s be honest with ourselves, despite quality tests, quality workers on assembly lines and programs to look for and take out such malformed boards and pieces, there are the cases of those pieces which slip through the cracks and sneak into the boxes.
All I can say is yes, contact Wizards of the Coast and have pictures aplenty for evidence, as, I suspect that as this issue goes on, they may become more stringent on requirements for replacing pieces, or, they may simply put this edition out of print either temporarily or for good if this keeps up.
