I hope my contribution helps.
Orianna should in itself be a character who at a distance: deadly, accurate and effective.
That's why I paid no attention to his defense.
Your big advantage is that your weapon is unpredictable with one another without the opponent at the "Lane" may very well kill. Take time for life to tickle your opponent down. Usually remembers nothing of your comparison. This game I would recommend you to one-half of his life. Does it even as if you go back to the base and attacked it from the hedge.

There is just no Champigon, take the chance and pushed your own lane, be it necessarily selfish because her a lot of "farms" have to pay for your equipment.

After the phase lane you should have enough money together have to be strong enough also to be no chance in a 1v1.

Have fun
