Stiff joints

Hey everyone, i've been buying some figures for a 2006/2007 collection and i've noticed all the recent figures made in the last 2 years or so have incredibly stiff joints in some areas. For example i bought the E49 Randy and his arms are so stiff it feels like a risk trying to pose him in the classic Orton pose, the Walgreens HBK is fine except for his left leg which the thigh swivel seems like it's glued in place, i received the Walgreens HHH today and similar to Orton, his left arm just doesn't want to go out no matter how much i try. I also got the HOF Sting a while ago due to a mixup from Ebay and his arms are also similar to Ortons. However some new figures i got are perfect, King Booker, Cactus Jack and HOF Edge have no issues at all.

Is this a common issue with newer figures and is there any way to fix this? 

Thanks
