A Couple Things.
Gangplank's Q should be a skillshot, not a point and click 400 damage that applies on hit effects. Gangplank's W doesn't need to remove ALL FORMS OF CC, while being a heal summoner spell. (Yes to all the 12 year old kids thinking they're so original with their "THEY JUST PLAYED AGAINST X CHAMPION, QQ THREAD)
Rageblade should be a Melee Only Item
Vayne needs a mini rework due to her reliance on Rageblade
Nunu's W needs a hitbox fixing
Mordekaiser needs a complete rework, so he doesn't have 200+ bugs.
Lucian doesn't need another buff just to sell the fucking skin.
Why is Riot nerfing Sejuani? I literally never see her in norms.
Electrocute got nerfed, so why not Dark Harvest? If the point is to remove damage then why not nerf all Damage?
Conq. is a bit strong on almost every melee champion. Almost all top laners go Conq just because it deals like 500+ True Damage in 5 second fights.
Conq is so strong in fact Tanks are absolutely useless.
