You made very good points and I agree with you wholeheartedly. The rush to get out so many core MOTU characters is, IMO, the reason why the subscription rates have gradually lagged. The other problem is that POP was never as popular as MOTU. I wasn't a POP fan as a kid and She-Ra was the only figure I owned from POP back in the 80's. MOTUC has mad POP so much cooler I can't imagine an MOTU fan not wanting these. Of course, I feel the same way about the NA figures appearance in MOTUC.
The whole line in my opinion has been brilliant...except for the execution and the disproportion of core MOTU figures vs. POP and NA.
