I've been farming heavily since the update and have found only 3 (THREE) Rakeipa on rune nodes.
Given they are used in so many recipes and blueprints it seems odd.. they are hard to get than the other so-called 'rare' items.
Possibly people are farming the nodes and just removing the Rakeipa leaving the rest which is something I was aftaid of but given how many nodes I have harvested in the last 2 and a half days I should have found more than 4.
Just wondering about the drop rate. Makes a huge number of the blueprints and recipes I have found and bought completely unuseable. I don't mind farming for stuff, love it in fact, but c'mon.. there is not hardly any in stores and the few that are there are asking prices like 20 for 20K. Doh.
