I'll be honest, I didn't even notice that. That's terrible. Maybe if the list of Pokémon Fast Balls worked on was properly fleshed out they would have been added?Incidentally it's very funny that the roaming legends are not on here so even if Fast Balls worked properly they still wouldn't work better on them despite al the old advice of the time going "use fast balls, since they flee!"
Putting aside issues like Pokémon distribution and level curve, for as many QoL aspects GSC added to the series and as influential as they are, they're kinda held together by toothpicks and tape at points. I guess that's the natural result of them using nearly the entire space available in the cartridge.
