How its working now?
The damage of the 2 spells http://www.wowhead.com/spell=157333/soothing-winds and http://www.wowhead.com/spell=157348/call-lightning is low. The formula which is 30% spell power of the Shaman, and 39% of spell power for Call of Lightning should be checked.
http://www.wowhead.com/spell=157348/call-lightning should be the first thing the Storm Elemental casts, and he should always get a higher priority to that spell if it came out of CD. Since the the CD is 10seconds and the buff stays for 15 seconds, then he should have that buff all the time.
How it should work?
Both Soothing Winds and Call lightning formula should be fixed.
Call Lightning should have higher priority when its not on CD.
