Well, I simply disagree. Maybe having this time gap of 12 hours between servers would be nice just for the sake of fancy, but any other features regarding exclusiveness I'm pretty feeling it'd create more problems than actually improve the game overall.
And considering the problems bias in this opinion, this is where I think devs efforts could be better focused in providing the game with more MMO features to make it a bit more like "real life" in pokemon world.
I mean, IMO it's the best Poke MMO around by far but still at some point everything narrows down to PVP and Poke hunting (i won't even metion PVE here cause in a sense it's a bridge for PVP afterall anyways), and these kinds of game should have more features for players having a good time with their friends and feel that world is more than just battles and completing poke dex (that's what the original offline games are!).
So basically, just quoting an example right away about that, till the present time we still don't have Hoenn Poke Blocks Contest, this is really a cool thing people could be enjoying altogether ingame, rather then just logging for grinding for battles. And I can't even supose the reason why there's no focus on implementing that. More contests could be included ingame like Fishing maybe (more ideas could be added here), instead of have it only promoted by community members.
Everyone comes to play for beating story mode and getting the best pokemons they want, but the thing is at some point people still wanna play but do different things. And these "different things" that I still feel PRO heavily lacks. It not only needs to be different but enable people to enjoy together. That's the big deal of a massive multiplayer game online, specially in one involving Pokemon world.
