If you got to redo the Pokémon games as you saw fit, what would you change and how?
Personally I would restructure the whole type system, by merging some types and changing their resistances, immunities, etc. My suggestion:
Elemental types: Grass (Bug), Fire, Water (Ice), Earth (Rock), Air, Electric
Other types: Normal, Fight, Metal, Dark (Poison), Mystic (Psychic, Ghost), Legend (Fairy, Dragon)
Pokémon of all combinations would exist, so for example you could get an Electric/Fight or a Normal/Dragon Pokémon. There would not be any changes to Pokémon’s evolutionary stages, i.e. how many times Pokémon would be able to evolve (No evolution, One evolution, Two evolutions), but all Pokémon would have Mega evolutions and only three Pokémon lines per typing would exist – one for each type of evolution (The exception being Eeveelutions).
You would evolve two-stage elementals with rocks and three-stage elementals by leveling up and you would evolve two-stage others by trade and three-stage by leveling up. The No evolution type pokemon would be the legendaries.
As for attacks, the elemental types would have more weaknesses but have a slightly higher BST to compensate. One immunity per type.
