Why does every type need to be balanced around a competitive scene that is unimportant to the main story? Shouldn't the competitive scene always be placed after the main story of the games?

Dragons should be rare and powerful.

Bugs should be weak, but evolve fast.

Ghosts should be rare and focus on statuses and de-buffs.

Making the same move for each different type diminishes their uniqueness and using a fire pokemon should require different strategies from a water pokemon.

Every type should have a distinct gimmick.

Psychic being over powered in Gen 1 makes sense given the lore of the type.

If you disagree with this, then you are one of the reasons the games suck now.
