When I read it earlier today, I was thinking the whole chapter was very rushed but now I'm considering re-reading the last few chapters to get a more favorable pace.
I also think that Asuna's sudden "I know how to fix everything" and cleaning up in a few pages what took volumes to destroy was way to convenient.
The fact that the Magic World Arc has ended brings a tear to my face since it was undoubtedly the best thing that has happened to Mahou Sensei Negima as a whole in my opinion. I went back to read the first volume again just to compare and I couldn't even recognize the characters as the same ones.
Spoiler:
I wonder how much longer the story will last now that Negi's father has been found?
