Look, you guys ever use Double Team in game? It feels like the AI always hits you no matter what and it quickly becomes a waste of time to use. And then, whenever the AI uses it it's annoying to hit them and generally wastes your time.
That's what the sinnoh Dex feels like, a bunch of shitmons who are a waste of time to raise and incredibly annoying to fight. It's like they designed everything in gen 4 to be annoying as fuck and waste as much time as possible.
