About the Rarity Excluders:
Yes I suggested to remove them altogether and make them only available for event rewards. I’m also aware that they sometimes backfire and bring you a non legendary thanks to the RNG.
For the events price they’ll be obviously given out as neutral potions (just to clarify it now) and in larger quantities, not only one, depending on the placement (so that the 1st, 2nd and 3rd ranked get those, if the type of the event allows it)
If they should stay, they should get nerfed again, since they basically destroy one of the mechanics, PixPet Rarity, which kinda makes those rareness more common than rare pets. And that... kinda defeats the purpose of rare pets.
