Not to say that you're wrong, but it's also important to keep in mind that, at least in normal dungeons, the difference doesn't matter at all. I say this as someone who sacrifices some damage on trash (namely, 2-minute CDs) to be able to do full openers on bosses (because NIN opener is fun), so take that as you will.

That being said, Tenri Jindo is looking tasty on trash mobs, so I may have to reconsider in DT.
