Yeah, i think you may be exaggerating a bit there canuck. I have all the figures as do quite a few others here, and the last figures to have that sort of issue were scouter Vegeta and Cell, both very old figures at this point, and both with new versions either out (PCE Cell) or coming (2.0 Scouter) which are much improved over the old ones. SDCC Piccolo is perhaps a bit loose but not to that extent and SDCC Gohan has the arm problem but thats merely from reuse of the mold, hence why a new 2.0 was made of him.
Scouter Vegeta and SDCC/2nd reissue Gohan have the only widespread QC issues in this entire line as far as im aware, thats a very small margin at this point.
To reply to Snake: My Vegetas are fine, but one of my two Trunks has a loose left arm. Its likely as you said to be so they swap out easily and not a QC issue.
