Ok so picture this scenario:
We get 70 brand new Pokémon in S/M which are all unrelated to previous family members from past generations. Pretty much just like what happened in X/Y despite the Megas.
However, in total we get 100 new Pokémon in Alola, being 30 of them solely babies related to Pokémon from all the previous generations and that's it. How would you feel about it?
>IT ALL COMES TOGETHER
The only additions in the superior stages would be Megas.
So new baby Pokémon > Old base mon > Old 1st/2nd Evolution > new Mega
Only if the fully evolved version gets a BST boost

>New Ledyba baby
>Median gets a massive BST boost
