So, having bug reported this and sat on this for a while. The 10% chance to double resource node yield does not apply to survey nodes (rich, etc.).
Should it?
It says it does not work on it in the description if I am not mistaken. I think it works on non-survey nodes. Personally I think the chance for double needs to be upped if its not going to work on surveys.
I think the CP chance is turned off at survey nodes. The CP chance works by looting same node twice if it procs, and i have e.g. never received four mats from the "dual" nodes - always two.
My opinion: yes CP chance should proc on survey maps too. They are reward from daily quests which heavily limits their yield, compared to normal farming where is no such daily limit.
