The worst thing about how shit the Johtodex is how the game railroads you hard into using the Kanto pokemon. So by the time you actually get a Slugma, what kid is going to fucking pick it over their Arcanine or Ninetails? Even if Johto was less poorly designed and put Slugma in Johto, he's still outclassed hard by Growlithe and Vulpix.
>inb4 NOOOOOOOO JOHTO IS AN EXPANSION OF KANTO, YOU'RE SUPPOSED TO MIX AND MATCH INSTEAD OF USING 1 OVER THE OTHER!!!!
Ok but that's negated by the fact that a lot of the Johto Pokemon are inferior and most of the cool/good ones aren't available to get until near the end of the game, in the post game. You're given 0 incentive to use Togetic or Aipom or Spinarak or Hoothoot when you realize they keep fainting in battle. You'll end up swapping it out for Red Gyarados or Armpharos. They couldn't even make the babies available in the wild so you could use Kanto via new Johtomon. Instead, the babies exist purely so you can breed Kantomons very, very late in the game, get the Johto babies, then store them away forever just to fill up the Dex.
There's a reason why like 99% of the time someone's Johto team will have either Crobat or Ampharos compared to how diverse a Kanto/Hoenn/Sinnoh/Unova team is
