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
It’s one of the top 3 most popular starting items on a few top laners. The most popular one on Illaoi, too, bought in 60% of her games (probably same thing for some other champions too, I just don’t want to individually look everything up).
