YES THE SHOULD!
To make some creative starters this time,it would be best take soe different types. Hopefullly Dark/ Psychic/ Fight.
Psychics learn more than JUST Psychic moves genius.
No need to call me a genius, thank you.
Typical to the starter types:
Grass -not very effective- to Fire V
Fire -not very effective- to Water V
Water -not very effective- to Grass V
Dark -not very effective- to Fighting V
Fighting -not very effective- to Psychic V
Psychic -NO EFFECT- to Dark X
See what I mean?
Only Fighting/Rock/Flying would work:
Rock -not very effective- to Fighting V
Fighting -not very effective- to Flying V
Flying -not very effective- to Rock V
This would also make the first 'pure' flying Pokémon line.
Ever thought that A Psychic type can have more than one type? Apparently not. -_-
Then we're back to dual-typing, what's wrong with for example, Grass/Rock, Fire/Ice and Water/Flying.
Starters MOSTLY start with the same type, I'm trying to make a point with single types only.
And why not make the 'Dark Starter part Ghost, then it'll be immune for 2 things, oh and give it levitate, then it's immune for 3 things.
Dark is just a type that unbalances a starter triangle.
Did you forget Bulbasaur? It's Grass/POISON No one ever complained.
My idea for dual type starters was: Fight/Water Dark/Fire Psychic/Grass see?
Those work just fine.
I think they should keep the same base types but change the secondary type, torterra was able to super effect both of the other starters, and Empoleon was at a disadvantage to both starters (unless, of course, u werent being a noob and taught ice beam).
If they made different secondary tyes that formed a ring of super effects, it would be good.
