Quality has gone through the floor since 2011 to the extent that I've basically stopped collecting. I used to be a fairly broad consumer of the franchise - absolutely loved the movie line figures, didn't particularly like the Animated show but got most of the figures, and got a fair whack of the Generations/Classics stuff too, but no more.

The last six new Transformers toys that I bought and actually enjoyed were

Gen Springer (April 2013)
DoTM Human Alliance Roadbuster (Jan 2013)
MP-13 Sideswipe (mid/late 2012)
MP-12 Starscream (June 2012)
FE Prime Cliffjumper (Feb 2012)
DoTM Human Alliance Soundwave (Feb 2012)

Basically everything else I've seen from DoTM and Prime's mainline going forward has been absolute garbage to the extent that for the first time in literally about 16 years I don't even bother to keep up with what's on the horizon, what's actually coming out, and what's hot.

I don't know how much that would affect non-adult collectors but it's basically killed off most of my interest in Hasbro and Takara's stuff, and now my purchasing pattern is older figures that I missed and feel like I'd enjoy and third party stuff.
