With POTF2, Ep 1, and POTJ, there were some specific issues that cropped up from time to time but in general, there weren't a lot of paint problems. Now we're on year 3 of the Saga line and it seems like the more figures I see lately, the more paint slop I come across. Stuff such as eyes being different sizes from each other, eyebrows taking off halfway up the heads, hair bleeding over or being partially unpainted, pupils pointed the wrong way (aka "googly eyes"), you probably know the type. At first I thought it might be just early batches of these figures, but I'm seeing this fairly consistantly throughout the figure's run now.
I do remember some pretty big slop issues with early Saga figures, most notably Kit Fisto, but I dunno, it seems like the slop problems generally don't feel as bad up until about the middle of last year, and then started growing and growing from there.
