Nah. I liked it as a gimmick in Black and White, but at this point I just want as many Pokemon in a Regional Dex as possible. Plus, I appreciate that the design mentality for the last two gens has shifted to making the vast majority of new Pokemon fill some sort of niche that makes them unique, whereas if you had to fill an entire region with new Pokemon, most would have to fulfill a more general role. For instance, the Reuniclus and Gothitelle lines were essentially clones of the Alakazam and Gardevoir lines, and as a result are fairly forgettable in retrospect.
