I feel like Gangplank's parrrley needs a change

I don't know what is the problem with Gangplank but from reading the boardsa nd reddit I believe it is his Q that is a ranged melee attack.

I see why Riot would want to do that; you can't always rely on barrels to slow down enemy. There are Deadman's Plate and Iceborn Gauntlet and Frozen Mallet. Also, Hydra - for the same reason, barrels can be hard to hit in the heat od the battle and Hydra boosts the AoE damage from Gangplank. With all that being said, this brings few problems. Parrrley needs a target. Parrrley procs Bandit mastery. Parrrley crits and applies on hit effects.

I am wondering why Riot didn't make Parrley a cone-shaped skill shot (something like Kled's unmounted Q). It would no longer Crit, you could boost the damage in face to face combat, it could ve made to crit, but with custom scaling and it could be made to still trigger barrels, only you wouldn't have to feel like threading a needle when trying to trigger it.

Shift the burn from his passive to his Q; if he Qs a barrel chunks are propelled in a cone to set enemies on fire. His new passive should revolve around Critical Strike; GP was always a crit monster, and even now he relies a lot on crit to deal massive amounts of damage. It should stay the same regarding the movement speed, but it's cooldown should be reduced on a Critical strike, be it barrel explosion or AA.

Give barrels AD scaling that deals reduced damage to minions. This should encourage GP riskier positioning to line up Q and damage to clear a whole wave.
