. The main aspect of Pokémon games is the single player adventure, not the competitive. Some Pokémon are meant to be weaker because they're common and easy to obtain, reach their final stage much earlier, get stronger moves early on, are easier to train, etc. So they're balanced out taking the in-game single player experience into consideration, even though those aspects are completely irrelevant to the competitive. Why would you use Squawkabilly in SV when you can have the Gigachad Braviary? Well, because Squawkabilly is a good early/mid-game Pokémon right away and it's much easier to raise, while for Braviary you're stuck with Rufflet until level 54, and it also has a slow growth rate. They both have their place in the game.
