The two nixed elemental shaman nerfs from Class Tuning Incoming – October 29 have been pushed onto the PTR via hotfixes. These below:
Echo Chamber now increases the damage of Elemental Overloads by 20% (was 40%).Ascendance now increases the damage of Elemental Overloads by 100% while active (was 150%).
These were reverted prior to being pushed onto Live during Oct 29th tuning but it appears they made it through to the PTR. WoWhead posted that the PTR received a bunch of live’s hotfixes so I am guessing these were forgotten to be removed from PTR and should be reverted.
Please fix this
EDIT
This looks to be fixed as of latest PTR build
