I have come across quite the bug that renders me unable to gain Focus on attack, gather from gatherable nodes, and cause mobs to T-pose or disappear upon their death. I have just gotten to the Nameless Pass. After unlocking the whisper, I began fighting some of the mobs here and realized quickly after a fight or two that I no longer gain Focus on my auto attacks / rune attacks (Chain Lightning, etc).
I’ve reset the realm / game each time it happens and when I load back in, all is good for a minute or two but sure enough happens again after fighting Nameless Pass mobs for a little bit. I do not have this issue anywhere else and as a result am stuck earlier content as I cannot really progress through the Pass.
