>>33205272>core trading mechanicsThey don't affect trade. Trade compatibility works the same way in gen 5 as before. Trade compatibility in general is a bad way to define a gen because it's always fluctuated. You know what hasn't? New Pokemon.
>??? typeChanging Curse is not a "core" change to battle mechanics.
>they can add new Pokemon whenever they want mid-genYou keep saying that when it's never ever happened, while your other rules have been broken. They won't do this, because they would be adding a new generation of Pokemon to an ostensibly older generation of game, which would throw generations out of order. That's why there's no such thing as "mid gen Pokemon."
>flimsy wayNo, it's the only objective way, because battle mechanics don't have a "generation," whereas Pokemon do. And the game they are released in is that same generation.
Legendaries not evolving doesn't change the legendary classification one bit. New Pokemon mid gen however completely changes how generations work. This isn't hard to understand.
