An 'offensive' Sona is basically one that revolves around her AAs because of the Power Chord effects. As such, she is sometimes played AD to take advantage of her AA-centric kit. She doesn't have that good scalings, but the fact that she has so much utility on-demand and has 'semi-steroids' (additional damage as well as a flat stat rise) gives AD Sona an 'almost-viable' status.
