Quality of plastic in Transformers

[Scattershot24]

Hi GUYS.
Ive started this thread because I wanted to know what your thoughts were on the quality of plastic on The Transformers of the last 2 years, the reason being is that i have noticed a lot of my DOTM figures have a lot of stress marks on them and certain TF prime figures I have also have stress marks. I also compared the plastic from the first live action movie toys to the plastic on the DOTM toys and the plastic is much better quality on the first movie toys, and even ROTF has better plastic also. I guess you guys have noticed but its putting me off collecting, I dont know if I should keep collecting new figures coming out or focus on collecting things from past era's I have missed but want.
