"Orianna is the most balanced champion in League of Legends" -Riot
utility mage oneshotting entire teams with q w r? yeah, pretty balanced.
atleast if you consider her to be balanced you should start buffing others on her level instead of nerfing everyone except her (and no, removing 3 base AD is not a nerf) thus making her the only balanced champion in the game while every single other champion is horribly underpowered.
"Ori's the most balanced champion? HA! You must be trolling!"
