@Nex:
! I'm assuming timestream questions will be answered come Christmas. I think this whole special took place in there. After all, why would he go back to Trenzalore?
! The thing is, because of how we know Time works in the Who-verse, the Doctor never destroyed Gallifrey. But he believe that he did. And that's enough.(Though, technically he did still commit mass genocide of the Daleks, and his people probably aren't okay, being locked away and all somewhere–that has to have some consequence.)
! And besides, is it that Moment that showed his commitment to saving the Universe, or everything he did after?
! Yeah I suppose that could be it. It just annoyed me a little that we got an epic to be continued…that didn't actually really continue lol.
! Yeah but up until this point we, as well as 9,10 and 11 believed that he had committed that horrible but necessary act, and that was a major device for the character development of The Doctor. The fact that he had to live with himself after destroying his own people, and eventually managed to move on, even though he clearly still carried heavy emotional baggage, it all just seems a bit cheapened by this rewrite in my opinion.
! Well everything he did afterwards was just the same kind of stuff he had been doing since he ran from Gallifrey in the first place. Using the moment underlined that he was the man that made the impossible decision for the good of universe, and now that's no longer the case.

And that moment has defined the show for eight years now, time for a change.
That just opens a nasty can of worms. By that logic pretty much any mainstay of the show is open to be altered. Would you say that's the case?
