Torment vs Fire
Well, you’d want to run fire or air if you’re running a power build since they both scale with power. Torment scales off of condition damage, so it would have little utility if you’re geared and spec’d for direct damage.
Even for condition specs, you’d generally would want to avoid grabbing precision since we don’t really have many useful crit procs – not to mention you can’t crit on conditions, so the precision will mostly go to waste. Grabbing precision just to see more torment proc (8 sec duration 7 sec CD) means you’ll lose out on more useful stat like power/vit/toughness.
