After the update previous to yesterdays, red 2* evo runes would drop somewhat consistently in Battlefield. Farming Point Of No Return on Madness, 3 at a time would drop 1-3 times per SoT-refill. Today I've playing through two SoT-refills without getting a single red 2* evo rune. So now I'm wondering if I've simply been unlucky or if the droprates have changed. I'm pretty sure I saw Sparton write somewhere that they didn't change any droprates but perhaps that happened by accident.
So, has anyone else experienced the same or have I just been unlucky today?
