I can now tell you've never played a real horizontal progression game.
so it has a ward to make up for less magic resistance and has more DPS? why would anyone use the piece that has lower DPS and just magic resistance?

there's no "real" horizontal progression game, there are many different ways to do horizontal progression. you're stuck on horizontal means absolutely no BiS which is not true.
