Yeah that's how they should have done it in Sinnoh, I read about their teams on the internet, Brock should have had Turtwig since it evolves into a ground type, and I've only watched the end of one episode in unova, and I must say, they got the wrong people to travel with Ash, it should have been Cheren and Bianca and the starters split between them, Ash gets an Ostowatt, Cheren gets a Snivy, and Bianca gets a Tepig. The splitting the starters wouldn't have worked in Johto because the only way that you could split it is, give Misty Totodile, and give Ash and Brock cyndaquil and chikorita, which neither has the right typing for Brock. I honestly would have liked to have seen Misty's team for Hoenn and Sinnoh though, I know that it wouldn't have worked in Hoenn because they tried to split the starters evenly and Misty with Torchic=fail, but it would have worked in sinnoh where she would get a Piplup. Also Ashes team in Hoenn was pretty cool from what I've read but why on earth wouldn't they evolve Corphish?
