Oriana is a support AP nuker: she has a shield, can zone and makes very good use of her and allied positioning. You have an insane potential DPS but you must place and manage your ball perfectly. She zones an enemy laner while farming easily without mana and can really make a difference when ganking.

Karthus is a kamikaze AP dps glass cannon, the only positioning you need to worry about is where the enemy team is; just run in the middle with E on, hit as many people with your wall as possible, land as many devastations as you can until you have to die, then cast requiem and some more devastations until you really die. A Karthus just freefarms with his devastations on his lane; done right he can almost achieve a perfect CS because he never needs to move from the lane: just press R during a gank.
