Lets add acc vs colbri, without a brd:
Everyone already knows that's a retarded EXP decision, though, so you're only skewing the results in your favor. I'll admit that Joyeuse is at a disadvantage accuracy-wise against anything, especially colibri, but honestly... who does Colibri sans-BRD/COR and actually pulls out anything remotely resembling a decent hit rate?
Well, this will be completely out of our comparison but since you asked: My DRG caps acc at colibri without food or outside acc. I hate acc songs/rolls as DRG, and since the advent of crab sushi, I think it's worth less for other classes as well. Both my NIN and my THF in the future should be able to hit in upper 80% using crab sushi without Mad.
However, we aren't talking about the best acc 2h job, we're talking about DNC. The main reason I left it out was because not everyone uses a BRD there, and it isn't as reliable as the sushi, which you can completely control yourself.
I don't mind factoring in a BRD though. Blade Mad gives 34 Acc without merits and at most +39 with merits(I don't think I'd merit mad though, probably lullaby and Minuet). Lets give them the best possible bonus excluding relic, and say 39 ACC from Mad.
Dagger will be capped acc, and joy will go from 64% hit rate to 83.5. Comparison in hits and Tp(using the BK+1 senario):
Dag/Dag will get 1826 landed hits, 9130 tp.
Dag/Joy will get 1769 landed hits, 9375 tp.
At this point, joy finally produces more tp, but still has less hits. We still haven't taken Saber Dance into consideration, and with the way DA normally works(joy DA does not stack with other DA), I'm pretty sure it will only help the dagger portion. In addition, the damage on Joy will be less, and you'll be surprised how little the 2 extra WS you earned actually helps with that(fast hitting classes like these rely on alot of damage done rather than big damage in ws).
Lets throw something else into the equation: There used to be a THF who frequented the alla forums for a while names Kwontoss. He held a then not very accepted view that it was better to spam sushi on birds and have double march than to have Mad sung and use meat. At the time, his view was more expensive and while he often proved his point(he did sick damage, had a very good haste build, so double march helped alot), most people couldn't pull it off. Nowadays however, crab sushi makes this type of situation available to us. Lets see what happens if we use March/Mad vs March/March, for both sets. I'll leave out RDM haste as it should help whoever wins even more. 4 Comparisons:
First, Mad/March(11% haste), haste samba 10%, 21% haste in gear as mentioned in the above posts. Still giving joy a better boost by maxing Mad, and not using Saber Dance. (42% haste total)
Dag/Dag will have a delay of 173 after haste, 2.883 secs per round, 1248 rounds in one hour. 2620 swings, 2489 landed due to capped acc, and 12445 TP.
Dag/Joy will have a delay of 198 after haste, 3.3 secs per round 1090 rounds in one hour. 1144 swings from dagger, 1580 swings from joy. Dag capped acc, Joy 83.5 acc: 1086 + 1319 = 2405 total landed hits, 12746 tp.
Now lets see how they both do with March/March(51% haste) instead:
Dag/Dag will have a delay of 147 after haste, 2.45 secs a round, 1469 rounds per hour. 3084 swings @ 85% acc would equal 2621 landed hits and 13105 TP.
Dag/Joy will have a delay of 167 after haste, 2.783 secs a round, 1293 rounds per hour. 1357 swings from dag, 1874 swings from joy. With Acc, that's 1153 + 1199, 2352 hits and 12465 tp.
As you can see, Mad/March works better for Dag/Joy, but March/March with 2 daggers works even better than both setups. I'd like to point out, again, that this doesn't include saber dance. For those interested, Azoth/Ermine with crab sushi and March/March looks like this:
Azoth/Ermine will have 159 delay, 2.65 secs per round 1358 rounds, 2851 swings, 2480 landed hits @ 87% hit rate for 12648 TP.
In conclusion: With Mad AND Crab sushi, Joy hits at at a respectable rate for TP. However, it doesn't not do enough extra tp to really warrant the drop in number of attacks, and the actual damage per hit of Joy(which makes up a majority of the hits in that setup). Furthermore, unless Saber Dance breaks the traditional DA rules, adding saber dance will favor Dag/Dag to a large extent, making Joy obsolete. To drive the nails in the coffin more, unless you're in a dual BRD party, you should probably be getting dual march instead of Mad on birds anyway.
