Concoctions should be able to be used with heralds.

I understand the nerf to poison concoction, but why does every other type of them need to be gutted with it? Even now, with the nerfs to concoctions, poison is still the best since it doesn't need heralds to clear. While the others don't have the capabilities to be used on their own. I propose that when concoctions are equipped, they pop up in your inventory as a weapon. Of course, they cannot be upgraded or modified, but this also gives the option of giving some type of modification case that can change the capabilities. Some changes include longer duration, more damage, and/or higher debuff frequency. I would love to hear some other opinions, it would just be nice to make them synergize more.
