Claw of Lightning or Rogue Epic for offhand?

Just to make sure there is no confusion, the 45k backstab number vs. The 80k backstab number is largely due to Ragebringer being slower, and thus more backstabs are done within the same number of swings tested for both weapons.

Vyemm Fang had like 270 Backstabs vs. 400 from Ragebringer. 270 / 400 = 0.675 x 80,0000 = ~54k backstab damage from Ragebringer vs. ~45k backstab damage from Fang in the same timeframe.

Without backstab Ragebringer does 45 DPS vs Fang's 57 DPS against the level 50 mob. 9000 extra backstab damage from Ragebringer over 850 seconds (the total fight time using Fang) is around 11 DPS. This is how Ragebringer catches up. Ragebringer loses around 12 DPS from a worse ratio, but gains around 11 DPS from a better backstab.
