I'm sorry, you are retarded. I'll help you out though.
YOUR ONE PARSE DOESN'T MEAN SHIT. I can outparse people (with a Hagun) with 0 songs when they have 4. Is that "case and point" for you that bards are bugged and actually lower your damage output? No? Oh, well, that sucks.
I admit, my math is not 100% accurate or conclusive. Sadly though, you are too incompetent to even realize where the accuracy issues are.
1. Defense doesn't matter, as was already shown. Try again. And if you're seriously talking about hitting for 0, then a: get DD that use food, and b: use common sense. CAUSE IT'S FUCKING OBVIOUS THAT HITTING 8 TIMES FASTER FOR 0 IS WORSE THAN HITTING FOR 1 SLOWER. As a side note, you may as well reconsider gear then too. OKote>Dusk. LvL41 Mask>Aces or Turban. Do I need to list more stupid bullshit for you? In fact, you'd be better off making all these trades and keeping your double marches, 'cause once you're hitting for 1s, attack is suddenly worth nothing again.
2. Level correction DOES matter. Too bad you didn't know this.

I could redo the math, but it'd be a bit silly seeing as:
3. I assumed ZERO PERCENT HASTE ON GEAR on my first comparison and TWELVE PERCENT HASTE ON GEAR on my second comparison:
"For this comparison, I am going to assume that any melee DD can manage at least 12% haste on their gear (Turban, Dusk Gloves, Swift Belt for non-mnk. Turban, Fuma, Purple Belt for monk)."
Do you SERIOUSLY want to use this for your minuet proof? 'cause holy fuck, the haste I left off that anyone with decent gear has makes up more than level correction (assuming you aren't hitting 8billion times per second for 0).
I assumed best case scenario all over the place for minuets, and marches still -easily- won. But you know what, we missed the real kicker:
"All of these calculations assumed that Minuet gave an equal boost to weaponskills as it did to your white damage."
Really, if you're talking about hitting for 0 and then you're using a fucking multi-hit weaponskill (noncrit), you're just an idiot and deserve to be shot. The second you start using Sam WSes, Spinning Slash, etc, haste's value skyrockets.
Go back to your bullshit parses. Go prove for me that gallant's roll does more damage than fighter's roll, because with your logic, I -could- prove it.
Minuet is seriously -never- better than March unless you're using summoner burned DD that skipped skilling up after.
