GP since his rework has been a nightmare to balance, receiving nerf after nerf, while still being played in the LCS. It's the Azir syndrome, where riot focuses very hard to make a champion unique ( and they succeed, GP is great dont get me wrong) but they forget to actually balance their kits and give them clear weaknesses.
My complaint with GP right now is that he gets too much self peel for free. Like movement speed buffs on top of slows and extra slows; it's really hard to punish him if he makes a mistake.
Like why do his barrels give him so much MS when he misses a champion? He tried to combo me; he failed, but he still hightailed it out of there.
his laning phase is so oppressive, when in reality he should be at his weakest. You can't touch GP as melee in lane solo. he will keep Qing you over and over, while his barrels grant him slows and speedups and big damages to outtrade you.
It's funny because he is so frustrating to lane against, that many laners will ask for their jungler to come dive him. And it works because he is super easy to dive. I ve seen Tobias fate get wrecked by dives many times. And it has happened to me as well whenever I play GP.
People don't like him. He is frustrating to play against.
