[Can't Get Any Ferrite]

I will try that, thx man. But do you know if the reason that im not getting any drops is because of my high warframe level?

[Can't Get Any Ferrite]

Hey guys I have been trying to farm ferrite on Earth and Mercury missions. On the forums it says you usually get a good amount of ferrite each run, but i get none to maybe one drop of it each run. I am a level 20 something Mag and rank 2. Why am i not getting any ferrite? Is it because of my high level?
