Every generation tends to bring something new to the game mechanics. Gen II brought genders, day/nighttimes, breeding, items, and the special split, Gen III brought double battles, natures, and an EV/IV overhaul, Gen IV brought the Physical/Special split and inheriting IVs, and Gen V brought Triple battles, Rotation battles, and unbreakable TMs. But what about Gen VI, and how is it going to revolutionize the core gameplay? My prediction here is that there could be an overhaul. What kind of overhaul? I'm not sure. Here are three options on what it could be:
Base Stat Overhaul - redistributing the previous 649's default stats as a way of nerfing the overpowered ones and buffing underpowered ones
Movepool Overhaul - Adding/Removing moves on a Pokemon's movepool without having to get rid of the TM overall (Ex: Removing Ice Beam from Water types without having to get rid of it as a TM move)
Type Chart Overhaul - Adding/Removing a certain type's advantage/disadvantage/resistance to give the lesser used types a chance
Which of these overhaul is best suited as a revolutionary change?
