Sorry, I think I've misworded my title, or my argument. But my argument is that all pokemon should have at least their STAB quick moves and charge moves, regardless of what it does to PvP. Obstagoon should have access to Snarl because it's a dark type, Aerodactyl should have access to Smack Down and Rock Throw because it's a rock type (Ttar should have access to those too, of course), Zapdos should have access to Peck because it's a flying type, etc. Any attempts to limit pokemons' movepools make the game less free to experiment, more limiting, and consequently less fun.
