Wait... Are you talking about runes or Evo runes? I'm swimming in runes of every color. I can't get Evo runes to upgrade my green talismans from 4 star to 5 star. I only get 1 per drop , and the drop about once per 50 missions (at least thee green ones). Drop info specifically show 3 star green Evo runes in battlefield madness and nothing. Underworld has about the same drop rate for green ones.
