haven't yet noticed any issues with the plastic on any of the Dark Energon deluxes. WELL...I lie, I've noticed some issues, but none that seem a real problem. It's mostly just something I've noticed a lot recently on normal figures too: that the parts don't seem to be getting trimmed up as neatly from their sprues/frames/etc before being assembled. Both DE Knock Out and DE Bumblebee have a couple of places where the cut from the frame is a bit messy. It just shows up a lot more on the see-through guys.
