Eltab
Lord of the Hidden Layer
Strike a balance.
If a PC wants something very specific, they are going to have to persuade a crafter to make it for them.
If a PC wants some legendary item from lore and legend, it is time for a quest.
If a PC wants a magic item so he can actually harm specific monsters (like fighting Werewolves require Silvered weapons), put something appropriate in an upcoming horde.
If a group of PCs between them have all the skill and tool proficiencies to make their own magic items, let them. Rarity determined by their Tier level, perhaps.
