Threats to Quinn with this build
I'm Kracl Kurama,
I've been playing since 3 years now mostly Normals .-.
My Ranked is as a result of that not that high. I'm a Silver Scrub but let's get to the guide.
I Maybe have to explain why I've choosen the Cunningtree. I like to play aggressive when I'm playing ADC so for me there are no reasons to take defensive Masteries. But for those who like the defensive way here is the Masterie I woud take: 18/0/12 (Resolve Tree - 5 Recovery, 1 Explorer, 5 Runic Armor, 1 Insight)
