I think by now everyone knows potions are rather useless. I want to suggest another use for them - alchemy
It would be nice if players could use potions to enchant or change gear like maybe 5x a day. So for example. Spend a certain number of potions to change one type of broom to another. Or maybe upgrade one gear to another, so maybe a broom to a fiber.
This would make potions relevant and sort after again. Right now it's only use is negligible and not a factor in the game.
