As the title suggests how do i break through this wall? there is only 2 dungeons i can run which drops gear like 1 or 2 levels higher then my lvl 45 gear, which makes inheritance a costly and slow way of doing it. all other dungeons require 7k to run. im doing weapon mastery as much as i can and equipping higher level runes each time. What are my best options right now or am i doing it all already? thanks to any and all that offer help and advice for this
