So over 3 days I've come to notice not a single rune set I equip is applying the 6th tier stat bonus to my character builds. This includes Runes of Strength, Surging, Chronomancer, Unread and krait runes to list but a few. I really hope a dev sees this post as I've reported 2 of them via in-game bug report but I'm afraid it's not noticed yet. I even watched my combat log chat to make sure things were properly being applied and can confirm nothing is working atm. (Should mention I have 1 legendary rune in my gear set currently testing without using the legendary rune)
