Healing Draughts

[AstralUniverse]

Healing Draughts are in a bad place in terms of PC trade/economy because of their ridiculously high base value, being a potion of 4th circle at CL 12. This is not a feedback about their strength or affect on combat.

When buying from NPC, potion of critical wounds costs you 280 gold.
When selling to a peddler, a healing draught can net you over 400 in some places, with appraise items, etc.

This means that if a player decides to sell healing draughts they cannot sell them higher than 280 unless the closest potions vendor is REALLY far away, but still if they do so, the result will often be someone buying the whole stack and then sell it to a peddler for profit with zero interaction.

The most obvious solution I see would be to decrease the base gold value of these potions but I wont deny this could have some ripple affect on a larger scale that I cannot foresee so maybe there's a better solution?
