Yup. Some are a little strange to pronounce but.... I'll just nickname my Pokemon and that'll help a bit. xD
Right. There isn't any reason to change N's name. I'm not really disappointed with Bel's name change to Bianca, but like you said, Bel was fine to begin with. I personally thought Cheren would have gotten a name change before her.
I complained about the names for a bit, and there are still some I dislike (my poor Pendra ;;), but hey.
At least they kept N; why would they want to make it something different? Disappointed that they changed Bel to Bianca; I know Bianca means "white" in Italian but you already have Bianca from the fifth movie not to mention Bel's totally fine.
