I was confused by what you meant, since I thought Gen 6 was already in this game, and therefore whether or not it were interesting would've been irrelevant. I'm checking skills in the game pokedex, and the skills I checked seemed to follow Gen 5 rules instead of Gen 6, in which case I drop the idea (I dislike unnecessary inconsistency). But on the chance that the answer I had obtained in the following thread is true:
Then I'll continue to voice that I'd like for an update to Future Sight to occur, and this thread should be about the pros and cons of such an update. I'd like input on whether or not we can balance these pros and cons (such as consistency, increased utility of a move vs. effort to implement the move) to a favourable enough position to allow for implementation.
The game as a whole, I agree to an implied point, would be largely unchanged by an individual update to Future Sight. But that's not a good justification against its implementation, as not every positive step has to be a great one. It is small steps and adjustments which accumulate and collect, that create a more balanced and interesting game of superior quality.
