OK, fine I get it; the cast for pokemon changes a lot, but why did Brock have to go after 13 seasons? I know the whole pokemon doctor thing, but why did the producers chose to do that know, after Brock being such a popular character?
I think they needed a new character for a whole new region, seeing with the whole "You have a Pikachu that's so rare here" sorta thing wouldn't really work if there were more non-Unova Pokemon. Cilan is similar w/ the cooking thing and he excels at pretty much anything.
