As long as GP has his Q the way it is he can never be considered some king of pirates
Pirates are adventurous, bold, and brave.
Being able to shoot someone with a point and click skill and have 0 interaction with them doesn't scream pirate at all. You're better off putting that on a new champ that's scared of fighting.
Same goes for Tryn and Pantheon
Pantheon suppose to be a spartan who normally are built tough for fighting and dueling people showing no mercy. Chunking a spear at someone and stunning them w/e they get near you and running isn't very..spartany at all
The only champ who fits some hardcore manly theme is Olaf. He's a viking who throws an axe at your face and bashes your face in and says fuck you to everyone when he ults and continues rampaging
EDIT: By this post I meant how they're usually played not how their kits are. You never see a pantheon trying to fight you they just mash Q till you back or low enough to go in. You never see a tryn fight until he reaches his BS spike otherwise he runs from any conflict. Same for GP. They don't fight you they run all the time. His Q should've been a skill shot
