Some more info about the TNS issue posted above, hopefully some of it is useful. I’ve found that turning certain spells off or on on the “DPS” tab spell list causes the TNS values to go crazy IF molten core is set to a positive value (this was done with the destro imp incin spec, and turning molten core to 0 stops the issue from happening in all cases).
The following spells send the TNS values way up (it makes each point of +1 crit rating, +1 dmg, +1 haste, etc…) worth about 30 or more DPS): CoE, siphon life, UA.
The following spells send the TNS values way DOWN (well into the negative numbers, around -20 for some stats): CoA, chaos bolt.
Note that changing the backdraft sequence to include or exclude chaos bolt does not cause the issue, nor does it change the fact that turning chaos bolt on in the spell list causes the issue.
None of the other spells on the spell list, including immolate, all other curses, corruption, all filler spells, conflag, life tap, dark pact, and pet attack, cause this problem. Turning backdraft off also does not cause it.
Hopefully there’s something here you can use. I love the spreadsheet and really appreciate all the work that goes into it, so thanks for everything.
