I did some dps test on the ptr today. 15 minutes each. I tried the following combinations.
WF/WF, lightning shield, SOE, WF totem, Mana, searing
WF/WF, lightning shield, SOE, WF totem, Mana, magma
WF/FT, lightning shield, SOE, WF totem, Mana, searing
WF/FT, lightning shield, SOE, WF totem, Mana, magma
WF/WF, lightning shield, SOE, WF totem, Mana, FT totem
WF/FT, lightning shield, SOE, WF totem, Mana, FT totem
I used this build. http://talent.mmo-champion.com/?sham...0&version=9626
Rotation was SS, ES, LL, wait for SS. repeat. I was throwing lightning bolts when 5 stacks were up and refreshing totems at 1 sec left. I didn't use wolves or heroism in the results I will give. They gave a flat increase no matter the combination.
Here is my armory for my shaman who hit 80 3 weeks ago. http://www.wowarmory.com/character-s...enas&n=Solonia
Results:
WF/FT 2592 dps with both fire totems on the heroic dummy. Magma was ahead almost 200 dps on the lvl 80 dummies since both were hit with the totem.
The other combinations ranged from 2200-2350 dps so not really worth discussing.
This is essentially identical to my results on live when you adjust for the better latency on live.
Buffed in naxx 10 I was pully 3700 dps on patch so I would actually expect to see a slight increase with the talent changes. 1 point in the new imp SS significantly increased uptime. I always had enough mana to make it to the next SR even with dropping magma.
Apparently they are changing the bonus to UR to be expertise instead of agi. If it is a decent amount then I would expect to see a fairly significant increase in dps.
