Gangplank no longer has an identity. Riot refuses to buff or change him.
In season 7, GP was known for his amazing late game, but his early game was complete dogshit and only the best players were able to get through and utilize barrels in mid-late game (WHICH TOOK SKILL, NOT JUST SPAMMING Q) to win their games and get good winrates. In season 8, GP was changed from a late game carry to a midgame fighter because of things like Grasp and Klepto providing so much gold/pressure and powerspikes for GP, building full damage wasn't required to carry as you could soar through the laning phase and be ahead of your laner already. Then the crit changes hit, not affecting GP that much because Grasp and Klepto are still strong against top laners because there is little armor and resolve has been nerfed so many times. Come preseason 9, armor runes are added, chyrsralis is removed and bounties based on CS are added. Here we have a champion who is no longer a mid game fighter like riot tried balacning him around because his Grasp poke means nothing and Klepto isn't as effective. He is no longer a late game carry because Crit itemization is horrendous and his ult without TLD is pretty useless late game besides the slow. I want riot to take a good look at GP and either pick one of these identites because right now GP feels like garbage to play. It's really frustrating to play him right now.
