I see where you are coming from Icey, but over here in the UK you don't really get DW mentioned in the media without a reference to the regen limit (and usually Tom Baker, lol). It may be different in the USA but I really don't think that there are many new fans over here who don't know about it if I'm honest. If it's a case of SJS and Jo knowing about it and Amy/Rory not then why can't those two come onto the main show and do this?
I just don't like something that I have known about for 35+ years being dealt with on a spin off, it's just wrong. It has nothing to do with RTD being the one to do it for me, if he had written it for the main show then I think he would still get a bashing
I really don't understand why it divides the fans so much, they want to create a drama between two mates that just doesn't exist.
