Sorry, I think I do not understand what you are saying. Are you saying that you think the potions are automatically created without using any of the ingredients in the inventory? You definitely need those ingredients in your bag or they aren't created during meditation.
They are, it uses only your alcohol, which makes no sense.

It's no matter of immersion. Now the entire system is completely different. You have to pick up very specific herbs to create a potion. Whitout the autorefill, the game would turn out in hours of grinding.
In the previous games, you needed generic herbs.
So why not need generic herbs again, why remove the chemical element system that worked so well in both previous games?

Since both ways are liked by different people, i personally think that this would be the best option:
Witcher 1 potion system with small edit box somewhere at the brewing window (for every potion) where you can specify limit you want to autoreplenish. If set to 0, it wont replenish and waste alcohol/ingredients. That way, people who like autoreplenish can set potion limits according to their play style and people who like to get their hands dirty can make all potions manually. Best of both worlds i think!
The issue with that is that they completely castrated the depth of the potion system found in TW1, which meant that if you do get your hands dirty, you could make way more potent potions than someone who just clicked "make Swallow", it was brilliant and probably the best alchemy system to date, so sad they decided to remove it because children have ADD.
