I've only gotten to attempt this boss in LFR so far, but since the fight is pretty long, we decided to pop lust at the beginning and have it back up at the end. With lust and a proc or 2, my CBs and Incinerates were WAY under 1 sec (about 0.6 cast time if I remember correctly). However, my Soul Fire was at 1.2 sec casts. Wouldn't it be more beneficial to use Soul Fire as a filler in those types of situations?
Would still be using Immo/Conflag/Corruption/BoD, but was thinking this would be a dps boost since you lose so much time with the 0.6 second casts.
Thanks in advance.
