Ultimately the only thing it made them do was have to animate flying animations for everything, not to mention the fact that ALL of the sky battles are completely avoidable making them completely pointless not to mention boring.
Had they stuck in inverse battles instead they could have made the game more challenging because you have to really watch your typing as it could be flipped on its head and it brings completely different look at battling
Now Pokemon with tons of weaknesses become super powerful when before they were just "into the trash" garbage mons
