Hi, I can see your build but it does not answer my question, why is the Earthquake's cooldown of 30 seconds not benefiting from the 2 Set bonus of the Spirit of the Earth?
Now I think I may have the answer. Using the Rune The Mountain's Call (reducing the cooldown from 60 secs to 30 secs) prohibits any further cooldown reductions. I am now using the Molten Fury rune and I think it works.
Also the key of the build is to spend ALL fury in one attack. Not for several seconds, it's just not effective.
I use full set Spirit of the Earth and the skills Leap and Earthquake. Earthquake is with The Mountain's Call and has a base cooldown of 30 secs. It appears that no matter what, the "Spirit of the Earth"'s 2 Set bonus (reduce cooldown by 1 sec for each 30 Fury spent) does not work at all, considering I am WW all the time, non stop, so I must be spending some Fury?
