Yea. I'm not 100% sure how, but I'm guessing it's because there is more time for my dots to tick on all 4 adds at the same time. When our caster is on SMN he'll keep all the adds dotted and when he's on BLM he probably bursts one set down before switching.

I could be completely wrong, but I do think my numbers are more likely to be higher with a SMN in t10.

Tell your NIN that you need Goad so you can Quick Nock 2 targets. It's a DPS gain when there are only two adds up. :P
