Still attainable, sure, but then that just leads to people just getting them via eggs and such, which is why this happened in the first place, you know? And having someone spending two weeks, as that's how rarity has been handled so far, on a route that may only be a few days or so to travel normally, is kind of unrealistic as it is. Logically, you might see something anyway. Heck, even in the games you might stumble across something and... kill it... without even knowing what happened.

The starters are one thing, naturally, but other things are probably going to get around. And things being rare is one thing, the fact is, a lot of things just aren't on there at all to begin with. I'll never get over Murkrow, a one-stage CROW Pokemon, not being around with Hoothoot during the night in the original GSC. But alas.
