What happened to gangplank?

I used to think that gangplank was a champion who sucked ass until he got his full build and then he would start blowing up both tanks and squishies. However he didnt really have an escape and since he went glasscannon positioning and staying alive was crucial and very unforgiving. Although i was always too bad to play him i tried to learn him and his barrel combos several times just because i loved late game scaling carry melees and he was also such a cool champion. I thought that his identity was the best late game hyper carry in top lane and one of the best in the game, but he made up for this with his bad early game. Maybe this was never the case and i watched too many tobias fate montages/videos but i would also hear high elo players speak so highly of his late game on streams and stuff. But now whenever i vs gangplank top lane he just abuses klepto and he seems more like an early to mid game nuisance rather than a late game hyper carry. He seems to just q spam brainlessly in lane and although he probably still requires a lot of skill he is really just annoying to deal with and not fun to play against since he plays like such a pussy champion with his heals slows and poke. Late game he loses 1v1s to almost every melee champ now since he doesn't really even do that much damage even if he builds full crit. On op.gg it says that his winrate is always in the top 10 champions between 0-40 minutes and even number 1 at minutes 25-30 but at 40 minutes+ his winrate drops to 38th lowest out of all the toplane champs. Idk man, i used to think so highly of all gangplank players and respect them so much for playing that champion due to his insane difficulty to master and bad early to mid game but now i just hate the guy and dislike everyone who plays him. Is this just me who feels this way or has he always be like this? I'd suggest nerfing klepto on champions that can abuse it and nerfing his early game q damage but also reverting the nerfs to his armor pen on his barrels only at rank 5. This would be so that he would be less annoying to deal with and still hate that late game hyper carry fantasy if he lands his barrels.
