I normally read these and just go with the flow of all the non-answers and mostly disappointment at the lack of information. But this answer really rang my BS meter:
"A: CG_Cyanides - The answer is actually due to some technical limitations. When we originally designed the Scavenger, we set it up for all gear pieces to be included. Once we got further in the process however, we had to make decisions on which pieces of gear could be converted as we could not support having all gear pieces included."
Are you saying that while having 96 gear scavenging options for Carbonite you can't do more than 12 for Electrium? Or 6 for Zinbiddle? That's a scam if I ever heard one.
Why can't you just be honest and say that you wanted to limit them so we would be forced to spend $/crystals? We all know that's the reason.
I think it's not content that is the most lacking from CG, but honesty.
