With preseason 8 hitting the floor in a splatter, most champions have had major changes to their gameplay for better or worse. Quinn is one that got much, much, much stronger.

To start off, runes reforged have significantly impacted every champions gameplay style and runes/masteries mean more than ever now. For Quinn, the Domination tree followed by Sorcery minor tree is the optimal way to go.

For optimal damage you can take electrocute, but I opt for predator as it allows you to do some major burst out of bird form and gives you a third movement speed active after youmuus.

Sudden Impact gives you a burst of lethality after you E, to get that extra little bit of damage in on those pesky adc's.

Eyeball collection is the real only useful rune for damage in the second branch of the Domination tree.

Since this build is all about the movement speed, relentless hunter is the only way to go.

In the Sorcery secondary, taking Celerity as Quinn is a must, when you get level 3 bird form you can get up to 300 bonus AD for that first attack out of bird form from this singular rune.

Gathering Storm is just for those late games where you need that extra 40 or so AD. Great late game and early for that bonus damage.

Finally, the items. Youmuus is a must. The movement speed active is killer on Quinn for both offense, defense, and moving around the map and the cooldown and lethality. Everything about this item is great.

Getting mobility boots might seem strange, but when you zip in at mach 5 and one shot the enemy ad carry or mid laner, it's worth it. You can also fly from lane to lane in about 5 seconds down the river, so you can split push all of the lanes at once.

Statik shiv for wave clear and burst damage, IE to follow for the massive critical strike to one shot the ad carry.

Bloodthirster for sustain, and finally a utility or damage item to finish and you'll be able to one shot anyone below 2500 health.
