Oh I'm on this, I have a plan. I didn't make that spreadsheet I uploaded for nowt! I'm not sure now why RiD didn't capture my attention at the time because I went all out on Armada, but having looked more closely at it, the diversity in the reused moulds and the original ones makes it an appealing line.
I have Prime and Magnus owned since the time, JRX boxed set bought a few years back, and now Baldigus, Scourge and Bludgeon added this year.
Yeah, CR versions have hidden rub signs over visible faction symbols, but there are a few paint app differences too. Pretty obvious when they're next to each other in vehicle mode. I nabbed these pics from tfu.info to showcase the differences [CR on left / RiD on right]:
