The best lanefriend you can have with quinn is blitzcrank one hook = first blood when blitz hook you use E and its just one or two basics and you have a kill its easy.

Quinn is a very good farmer cause of the passive on her W she gain attack speed every time she attacking an enemy marked with harrier (her passive) cause of that passive on quinns W you dont need to buy attack speed at early game cause her E will mark the enemy with harrier so you always gain attack speed wile you use E so use that in every fight.
