Rune of Minor Mysticism, Where Art Thou?

I don't know if anyone else has noticed but for some reason I cannot find a minor rune of mysticism anywhere. Did Anet do away with them with the derv update? Is it possible for merchants to run out? This has me baffled and I would love to know the answer.

Edit: ignore this thread and mods plz close. they suddenly reappeared...

Supply and demand. Everything at the npc traders come from players selling to them and current demand for d/ stuff since they're actually useful now means limited/no remaining stock at the npc.

Yeah they basically can, and their prices will rise as the demand rises.

Needless to say, i made a fair amount of money off of tomes/runes that i stocked up on before the update

Just park at a rune trader with a PRIMARY derv character and keep pressing space,
often you get lucky and see a new minor myst/scythe rune appearing within 5 minutes of pressing space.
And when you do, buy it, don't even hesitate on the price.
