To be perfectly fair; it's going to be a hard task to get a solid comparison using fights from ToT period. So many of them have damage buff or reduction mechanics, immunites or submerge timers that accuracy is all sorts of off for a variety of reasons.
Our only real patchwerk this tier also includes a straight-up 40% damage boost, and most other fights have multi-dotting; phase transitions or the like. It's sort of like how tier 14 was abominably skewed in favor of DW Frost because nearly every fight had some kind of cleave phase going on.
