Which is fine if you build a comp around that idea. And that is more than likely the reason she is not top tier.
IMO Orianna fits the meta perfectly. Solo or duo lane, I've been able to freeze and stay in lane. I can shield my jungler fairly easy due to the range on Protect. Her CD is next to nothing. She can even jungle herself at level 4 and almost take no damage. Duo lane, we can out harrass the enemy team due to Protect constantly soaking damage. Her range is good enough to poke and lane and not get jumped on.
