Start your sentences with capital letters and end them with proper punctuation. Don't start a new line every time you start a new sentence.
Dummy tests aren't useful unless you have very consistent players, testing for very long periods of time, with dedicated friends willing to provide all relevant raid buffs and debuffs. We don't use them here, except for specific tailored theorycrafting purposes, like establishing proc rates and internal cooldowns.
The searing totem targeting issue is very (very!) old news. Read before posting. It will attack the level 83 dummy in Orgrimmar, but it ignores most other dummies.
Your results for establishing or confirming a spell priority aren't helpful if you don't show your work. Read this post:
Made the changes Rouncer talked about, rechecked priorities. Came up with this as highest:
I'm not an expert and still bit new with Enhsim, but as far as I could see, this priority was comfirmed when analyzing damage meter, after doing rotation on test dummy for 20 minutes.
another problem is, as for now ST doesn't attack a dummy (just me, or other people having this?)
yet still: average damages: LL > LB > FS > ES > SS
just a matter finding out where to fit cooldowns and ST refresh
