I dont believe corruptin pot should be in the game
It gives sustain and damage to champions that typically already run the lane, it makes trading into a match up with someone with one go from a skill based match up to an automatic loss since by its nature it provides a strength that riot trys to avoid at least when designing top lane bruisers and that is mixed damage with
being the exception to the rule.
I recently played as yorick and built corrupting pot as you do and there was practically nothing renekton could do to stop me after hitting level three, i also ended up on the receiving end of this in a match up versus an irelia who also brought conqueror which meant she was doing physical magical and true damage in mass. I dont see a reason that this pot needs to exist it seems to only be there to propagate champions that are contingent on snow balling out the laning phase by just pasting extra damage onto their kit which just feels aggravating to play against.
