Threats to Quinn with this build
This build works well for TOP - MID - ADC
If you have stupid enemy at "BOT lane" talk to your MID and Help him with assist or kils. That gives you advantage in gold.
::Playing against enemy Quinn::
Wait til she uses her Q, after that engage with "E-Q-E" or "Q-E-E" combo
Use "Woad Scout Quinn" skin, this one gives you a bit more neat arrowing on passive skill and easyer to spot it. It looks ugly yea... But ingame it helps.
