It's my feeling that if people do not report these to LEGO (without asking for replacements) and explain the seal situation, a fix will not be implemented.
Each incident should be reported to the merchant and to TLG.
Unfortunately, there is a huge and profitable market for minifigs,one which LEGO has not satisfied.
An secondary benefit of reporting the issue may be that LEGO eventually decides to make more minifigs available without sets, possibly at an increased cost or through a club.
