So the beginning of Hellfire has been going well. A lot of fights have ads to handle so Balance of Power has been getting used a lot more and shows a clear dps increase than using Euphoria on the same encounter.
One fight I'm unsure about is Archimonde. My guild has been practicing on normal and my dps has been abysmal for this fight. After a whole night of dying to the boss I couldn't find a clear favor for Balance of Power or Euphoria. My logic for BoP is that there are frequently three targets that need to get killed and later in the fight there is an increase in ads to handle. But for the first part of the fight I'm getting low dps because Euphoria would be better suited for bursting the Hellfire Spirit which has to die ASAP. But if I go for that my damage falls off later in the fight where I'm needed for AoE purposes.
This issue normally wouldn't bother me except for the fact that my raid's dps is very low on the fight and I'm on the bottom. Rather than blaming this on still using T17 while people above me have two pieces of T18 (because I don't think that's why my dps is so bad) I'm trying to find out what I'm doing wrong. I don't have logs available atm (posting from work lulz) so I'm analyzing this with the data I have right now.
TLDR: Is there a definite level 100 talent that is best for this fight or is all of the fault in my own rotation?
