The very notion of letting these be farmed and sold on AH? Why? so bots can take over the areas that drop them? And the drop rate … completely shameful. I’m sure the gold farmers love this. And now I see another rune that has to be farmed and can be bought on ah. You have completely RUINED the concept of runes. You took something that was easy and fun and turned it into a gold farming fest. I’m not even going to get them.
I got warlock notes first drop 
and found a dude with the cypher , together we grouped, summoned and got our rune. Total 5 minute investment
