Corrupting Potion was already barely bought by anyone and then Riot decided to give a huge buff to every starter item…except Corrupting Pot (and Tear).
Even in competitive play it has been a good while since anyone has bought it. And that is where the item was more popular due to the permanent sustain it gave
Why is it even in the game at this point? Riot probably forgot about it in the new season changes as well
Its not too bad on Jayce but the problem is you like to start long sword for early dirk w futures market (or dorans blade into assassin matchups)
