>>47227929I don't think encountering every Pokémon should be mandatory. Dunsparce is based on the tsuchinoko, a Japanese cryptid, and as such, it's ridiculously rare. If they made a Bigfoot Pokémon, I don't want it to be a 10% encounter in some common area. Hell, even setting it up as a set encounter doesn't feel right because it's a cryptid and cryptids are meant to be elusive. Dunsparce is cool because 99% of kids won't realize it exists in the game it debuts. Some kids will get that high luck and encounter it and rumors will spread from that, though the internet and guidebooks will also have that information. So let's say you learn about Dunsparce secondhand, and you realize you're only going to see it once out of every 100 encounters in Dark Cave. What do you do? Do you put in the 20 minutes or so that it'll take on average, just grinding it out until you find it? Or do you just ignore it and be salty? They could always make it a common encounter like Pidgey, but then again, literally nobody cares if you have Pidgey because it's so common in a number of games. Making Dunsparce common devalues it, it makes it just a thing in the game to check off rather than something rare to show off.
I obtained Munchlax a bunch of times in Platinum. Yes, I knew that it only appeared on 4/21 honey trees at a 1% encounter rate in Sinnoh and those 4 honey trees were individualized based on your personal hidden Secret ID. So you know what I did? I had shinies that I had caught, I calculated their IVs, then calculated my Secret ID from that, and then used Filb's honey tree calculator to find my trees. I then slathered those specific trees with honey every 12 hours for about a week until one popped up. Caught it, reslathered the tree, and chained them from that and got a bunch of Leftovers in the process which I wouldn't have gotten from breeding. This was also in the main story before I had access to Pal Park for Snorlax (though I could have just traded from my Diamond).
