Expanding on "Time of the Doctor", part 1 of X

In this post I explicitly want to limit myself to just the regeneration, and discuss both the 13-life limit and the "farewell tour."
I will give Steven Moffat credit where credit is due: the notion that the Time Lords could grant you a new cycle of regenerations was mentioned in The Five Doctors back in 1983, and that serial got a reference when the Doctor mentioned he nicked some Time Lord doodad off the Master while they were there.  Obviously without Gallifrey around anymore, there was a bit of a problem, but The Day of the Doctor sorted that out and as I already mentioned (3rd section) I really have no problem with the way they did it.

(Also, I find it interesting - although I cannot imagine this was Moffat's intention - that the Time Lords executed the Second Doctor, but then granted a whole new cycle of regenerations to a later incarnation that clearly took after him.)

I'm still holding out hope that one day they're going to do what they did in Logopolis and have a future (or "sideways") incarnation of the Doctor come back to shepherd him through his regeneration, and it would have been incredibly appropriate for it to have been now. But that didn't happen and I think I'm going to have to accept the notion that the Dream Lord from "Amy's Choice" was the Valeyard instead.

Speaking of Logopolis, here's the way that regeneration went down. The Doctor falls off a telescope tower and is hanging onto a cable. He sees various enemies taunting him, before his grip finally fails and he falls to his doom. After he hits the ground, his companions gather around him and he sees - very briefly - the faces of all the companions he had, and they all encourage him on. Then he regenerates.

Here's how the regeneration in The Caves of Androzani happened:

You know what's interesting about this clip? The only fanservice is Peri's cleavage. There's no interminable farewell tour like Tennant got. While all of his companions are present in the Doctor's dying, delusional mind, they don't steal the scene from the current one.

If we'd seen quick flashes of Amy, Rory and River, that would have been okay. But I thought we covered that whole "rebound" thing back when Martha Jones was a companion. Having an extended "Amy" section in the middle of the Doctor's regeneration (while Clara looks on, clearly more befuddled by the fact that the Doctor's talking to an invisible friend than sad that Eleven is dying) felt like backsliding. 

I don't understand why, to be blunt, that entire last scene between Eleven and Clara happened at all. Although I was amused by how quick the actual change from Eleven to Twelve was, I have a lot of grief to fling at the length of buildup to the regeneration. That is to say, after Eleven goes all glowy to nuke the Daleks, isn't that the end? Shouldn't he be Twelve in the next scene in the TARDIS? Especially since all his clothes are flung on the floor? That was particularly galling - the Doctor takes his bowtie off, just so he can put it back on and then take it off again. I guess my point is that, now that Moffat's changed the rules about how the glowy-stuff actually works, we can claim that the War Doctor ran around on a big farewell tour after starting to regenerate at the end of The Day of the Doctor. Hooray.
