Refocusing Quinn
Quinn is in a bad spot right now, she is a lower tier Adc and one of the lowest picked Adc. She is this way because, Quinn has 525 range, and her Ult brings her into melee range making her a really risky ADC. Because the style of her Kit basically makes her a assassin already, I suggest that Quinn be refocused to a Mid Assassin / ADC. To do this she needs the following changes, the stats were based off of Talon and Akali but reduced a bit:
HP 575(+85/level) from 532(+85/lvl) Hp regen 7.5(+.64) from 5.42(+.55/lvl) Mana 301(+34/level) from 268(+35/lvl) Armor boosted to 26.5 (+ 3.6/level) from 23(+3.5/lvl) Magic resist boosted to 32 (+1.0/level) from 30(+0/lvl) AD 56 (+3.2/level) from 51(+3/lvl) AS same Ms boosted to 345 from 335
R Cooldown changed to 100 / 80 / 60 Passive changed so that Harrier lasts for 5 sec, and Will Proc every 8 sec or 3 sec if Quinn triggers it. Vault cooldown changed to 11 / 10 / 9 / 8 / 7
