>>715744807 (OP)The first one is better because it means the typical player will never get a Dragonite, which makes the penultimate boss a lot more threatening when he suddenly whips out a team of dragons.
It also means that if you know about Dratini (maybe you saw the anime, maybe you memorized all the Pokemon, whatever) you can hunt for a rare pokemon and it actually feels rare. Then you have to train it and this makes it feel difficult and thus rewarding.
However, none of this is even remotely required to beat the game, which is piss easy, and that makes it fit in the game even better because it's an optional challenge. Nobody HAS to grind for a dragonite.
The right is just some lazy RNG. In that game you get a legendary for free and ride it around everywhere, so a dragonite is no big deal. Also this
