Yes im a Talon OTP for 5 years melee Q most of time it trolls you like you waste flash for kill enemy with Q and Auto for proc passive but it does Flash+Melee Q and enemy escape because you can't auto attack to enemy it is really sad and unfair bug because you are wasting your FLASH. I have idea for that think old Talon E it was a blink Talon was blink enemy behind with that way they can add a blink for 170 range melee Q when u melee Q you will blink enemy behind so no more bugs.
Backflip bugs still no fixed it is due to terrain's lines Talon has 725 range to jump walls so i can understand the backflip +725 range walls but under 725 range walls it is annoying.(Like turrets,Golem camp wall,Baron side's wall).
There is no info for Talon Q Range nerf so it has to be bug because as you can see from source Talon released with 550 range Q due to this bug you are losing trades against Xerath,Orianna,Taliyah(All range mages) they are just spam their skills and u just watching.
