AD Orianna is misleading. You want to built Attack Speed and AP, using items like Malady, Nashor's Tooth, Guinsoo's Rageblade, etc. Combined with the Spellblade, that's 35% AP on hit for the first hit, and up to around 40-45% on the third and beyond, in addition to MR shredding. I've out DPSed my team's AD carry with her, and there's nothing more hilarious than Orianna, the machine gun, queen of utility.
