Small sample size, but would like to mention that Aislynia and I on Valefor were doing some tests on a whim tonight, because our results from Chaos Roll were not coming back quite right.
TL;DR: after some quick testing on DRK and COR, there was a sizable discrepancy between our relative gains from Chaos Roll. We then added my alt's Samurai into the testing, and her numbers came back equal to the COR. At this point, we suspected Smite was the problem, and so brought my alt's Samurai back out with /WAR for Smite I. Sure enough, gains from Chaos Roll began to diverge between the Corsair and SAM/WAR.
what's probably going on is that the Smite ATK bonus is not being calculated as our "base attack" for buff spells and effects. I am not sure if this is already known, the search function keeps crashing for me. >.> I am also not sure if this is intentional on Dev Team's part, if they didn't want twohander DDs to get too much more edge with the attack bonus, but I feel it worth pointing out that this is going on, because it's also affecting hand-to-hand weapon jobs (namely MNK and PUP) and they are not presently in a good place; the relatively small Smite bonus they already got is now even less meaningful.
Should point out that Last Resort from DRK is also affected, so far as I can see. >.> Our own buff is getting nerfed by Smite.
Any mathy people wanna pitch in? I'll post some initial data tomorrow once I'm not 3/4 asleep.
