(Glyph, epic dark runes) Drop rates are broken, hidden, invisible - no parts generated

I have been opening literally hundreds of chests, gold or better, lv30 and up, and not a SINGLE glyph of ANY kind has generated! I’m a beta player, so I have a head start and all of my gear is stuck at lv35 and my gear level is still too low to jump on legendary parts. Not a single epic dark rune has dropped either! C’mon devs, fix the drop rates and stop leaning on the whales to be your solution. I’ve spent way too many gems on just TWO times and the natural gem rate is too anemic to build up any momentum on legendary upgrades.
