I get that Gangplank is strong right now, and nerfs are arguably justified

But you're just nerfing him... Wrong. I don't know how else to put it. Just a few patches ago, you made his barrels have a 0.25 second delay, and that was a REALLY shitty nerf, and I'm not saying this as a Gangplank player, but it nerfed the damage output of it by making him less rewarding of skill, and in general just feeling clunky to use, but removing the mana on kill if you kill the unit just plain doesn't make sense. All this accomplishes is harming his early game even further, where you have to farm like Nasus while being weaker than him at the same time. He already had a dreadfully abysmal early game where you couldn't even escape a Cho'gath with no boots (Okay, that's probably an exaggeration) but maing him more mana hungry early game and rewarding skill even less? If you want to increase his mana consumption without penalizing skill, just make his barrels cost a small, but considerable amount of mana (20-35, maybe?)

Also, who thought that Cho'Gath needed buffs?
