Some interesting changes are coming to all the specs, as far as dps goes our aoe has been a topic of interest as far as corrections and blizz has some ideas for us.



We start out with Elementals removal of Chain Lightnings CD and Increased Earthquakes damage by roughly 75% but to balance out the massive damage the removal would bring, they also removed the duration stacking of Flame Shock from Fire Nova damage.


On to Enhancement, we all know by now Enhancement aoe was more or a chore and very lackluster compared to other dps in raids, the ramp-up time it required to be competitive with everyone elses was far to long, making aoe all but useless, some would even go to the point of single targeting in group trash pulls rather then put in the work.
Well Blizz heard your cries and did something about it. they went ahead and added a new feature to Improved Lava Lash by allowing your Lava Lash to spread the targets Flame Shock to up to 4 targets within a 12 yard range, what that means is now our ramp-up time is greatly reduced and allows for maximum aoe.

Now on to Restoration, we have 1 change to a core talent, 1 to a core ability, and a tool-tip addition. First the tool-tip, all it is informing is that the occurrence of  Cleansing waters heal can no longer go off each time a target is cleansed but can only occur once ever 6 secs, basically stating a 6s CD which was already in place but was not noted.

Now on to Ancestral Healing, a new effect this core talent gains is a 10% increase to your healing targets health pool, now as far as it being base health or scaling with gear remains to be seen it will be something I will be testing out and reporting on soon.
And Finally we come to Riptide our sol castable HoT received a healing effect increase, so what that means is our HoT Effect post Riptide will do much more healing, and not the initial heal. So by no means will both these changes rocket us to the top of the meters but will bring a solid buff to aoe damage situations and Main Tank healing.

I'll continue to keep you updated as changes come in.
