Since no one has a real motivation to use pots (Urns take the same space and have more slots) I was thinking of changing them to small containers that can carry liquids. Their capacity shouldn't be nearly as good as a barrel's but they could be used to store wine without having it turning into vinegar, they would also be a very good option for beginners.
The storage should vary between 30L-50L and this would make more players consider making them.
that's all
