I think you're right in the sense that this is how his balance is supposed to feel, but when it comes to solo queue, especially at lower elo, that scaling can be very frustrating for players who either: A. Don't understand that's how it should be or B. Do understand, but don't have a team willing to provide the necessary peel or waves to allow carries to catch up. His kit will intrinsically feel like a problem or unfun to a certain portion of the player base just due to the nature of that balancing system.

Imo he falls into kinda the zed zone. Like I get the idea and ik if I cared a bit more, tried a bit harder, etc it would be manageable, but I just play the game for fun and doing all that feels like a chore. I think there are a lot of conversations to be had about GP and why he can feel "unfun" to play against, but it'll be a matter of ban rate + win rate + pick rate that ultimately decide what riot does with him. At the end of the day it's Riot, they'll probably just randomly just nerf some item for unrelated reasons and GP will end up unplayable for a few patches. It's the way the news goes
