Once thing that annoys me in PF is the cost of consumables, both as a player and a GM.
The cost/benefit of a consumable usually works out to it being better to sell the item and save for a permanent item instead.
By the time the party can afford consumables generally they just aren't effective or have player abilities that do the same thing or are just better.
Which means as a party reward it's just gold with extra steps.
My solution? Just divide the price of consumables by 10.
All of a sudden the party is keeping them on hand, happy to take an extra day or two to do crafting and multiple players in the same campaign are taking crafting feats. Which gives the party a little more sustainability which gives GMs a little more wiggle room in the XP budget for encounters, especially if you want to do a series of fast encounters.
The only problem we've found with this so far is scrolls, for wizards learning new spells they become way to cheap.
The solution is the cost of transcribing a new spell into a spellbook is the difference between the new cost of the scroll and the old cost of a scroll. So it ends up staying the same.
