Currently the “FA” rune has a much lower proc chance for its effect that lists a 6% chance to reduce enemy attack and movement speed by 20% for 3 seconds. No improvements with 2 FA runes either. Please increase/adjust its proc chance to match the description of the rune.
Over 30 seconds i was only able to proc it 3 times with 1 or 2 runes alike with max attack speed. Its clearly broken.
I’ll have this looked into, but in the future, please remember to post things like this in the Bugs Forum. There are people that monitor that forum and can have this investigated faster than I would be able to.
