Just pointing it out. I don't know who expected this to be normal paced, the moment we got to know that the aogiri arc was going to be in the anime you should have known that there's a minimum of 3-4 chapters/episode (considering 26 episodes, which most likely won't happen).
In the trailer they show the fight between Kaneki and Yamori, that's around chapter 65 or so. They could stop right after but finishing the arc would imply finishing at least volume 8, (we are not even done scanlating the aogiri arc yet).
We are talking about 79 chapters. No matter how, it was always gonna be fast paced. At some parts they'll have to skip certain parts or go through them really fast (for example. the fight between Nishiki and Touka, which isn't realy important, and more of an introduction for both characters).
Apart from that, I very much liked the 1st episode. I loved the voices and animation and even Yamori appearing there, I think it doesn't really spoil anything and would leave the viewer all along the episodes with the feeling they are lacking parts of information (definetely a good way to get people hooked up).
