I've seen that sheet. However, the math there isn't nearly as good as what I just posted
Some problems with that sheet (in order of significance):
- It assumes you don't use DoTs. That's a big proportion of your GCD damage (~18-19%), so that's a poor assumption.
- It does not account for the extra cooldown time induced by Raiton.
- Hence, it does not account for additional Trick Attack downtime, either.
- By putting it at the top of the document, it gives more prominence to the "additive buffs" theory--which has been discredited since 2013--than to the multiplicative buffs.
I've only now been putting a NIN model together after putting it off for so long, but the preliminary results suggest that using Raiton only is overall ~1 DPS loss at current gear levels (with an average ~10.5% GCD clip). So, not that this matters a lot, but I'm still pretty sure I'm right, neener neener.
