Now that I'm not half asleep I can answer this better. Snk can attest to the fact that I'm a pretty lol THF, but to take your points one by one, while still respecting the awesome advice you've already been given:
We could have a whole wide discussion around this, some gear to strive for:Everything from equipment
Generally my set looks like:
Weapon: Blau Dolch.
Sub: Viking's Shield (I need to buy a Tariquah +1, just been lazy)
Head: Lolahra Turban / O.hat (depending on what I'm fighting)
Neck: Ancient Torque
Body: Homam Corazza
Hands: Homam Manopolas (Dusk / Dusk +1 is an alternative if you have no luck with Limbus / have a lot of money)
Legs: Homam Cosciales (Skadi pants if you have luck with Salvage. Barabarossa's Zerehs if you can't get either)
Feet: Homam Gambieras (Dusk +1 again if you're having no luck in sea)
Belt: Speed Belt (Swift belt is what most people would have, and not having a speed belt by no means makes you gimp or awful)
Back: Amemet +1 (I sold my Forager's, yes, I'm a bad person. A Cuchalain's mantle is also an excellent thing to strive for, but they're pricey)
Rings: Sniper's +1 / Rajas (2x Sniper's is fine. If you get lucky on the ENM you can get a Toraedor's. There's also the excellent Divisor ring to shoot for)
Earrings: Brutal + Ethereal/Diabolos (yes, I was dumb for getting the Ethereal. A hollow will benefit your THF more)
I swap out things depending on what I'm fighting. If I'm eating attack food and I'm not satisfied with my hit rate, I swap to the dunce (Optical) hat. If it's absolutely atrocious I'll even throw the life belt back on. I have a Love Torque as well, but if you're not in an HNM LS, shoot for a Peacock Charm (in fact, if I'm using a lot of Ranged Attacks, I'll go back to the PCC.)
If you're not having luck with Homam, a Scorpion Harness +1 (or even an Antares Harness) are decent choices. Alternatively, if you wasted 10 bucks on ACP, upgrade your Mirke Wardecours accordingly. I adapted mine to a /NIN build (Acc. +10 / DW +3%) but you can probably adjust it accordingly.
WS gear's pretty straightforward. Strive for Heca, but if your LS doesn't fight Faf / no one will give you the abjuration, you have other options to explore -- I use a dragon harness for the body piece instead of H-Harness.
Generally full Skadi seems like a joke. It does offer some nice boosts, but sacrificing that much haste for other crappy stats and +5 crit hit rate isn't worth it. The body is a nice piece if you have money to blow, but it seems like you can adjust the ACP body piece to suit your needs and put the money somewhere else. As mentioned before, though, the legs are an excellent piece.
Subjob
Many people have posted a lot on SJs I already. It's nice to have /DRK, /WHM, /WAR, /DNC, /NIN for overall THF use. /RNG too, I suppose. At one point I was trying to level COR to expand my versatility, but I ran out of patience there.
When possible, I prefer sticking with /WAR, especially for something like Tiamat. I can see the case for a Mandau THF subbing /MNK because Mercy Stroke's going to stay the same at 100%, 200%, or 300% TP. For other jobs, I don't know, I'd prefer to build TP on other mobs while it's in the air. Not to mention that it's hard to outweigh the benefit of having the extra 10% on DA, and attack boosts through berserk and warcry (you can switch between them on landings, if one's down). I need to parse more (don't know of a good one -- can someone direct me to a safe one?), but at least according to my LS mate, while I was loling my THF damage, he assured me I was keeping up pretty well according to his parse. I never thought about it for Cerb, to be quite honest. Do you run into problems attempting to boost, then running in and hitting it just as it Hoplons?
The game is about more than dragons, though, right? (Shh, don't tell a certain person my LS I said that) and as I said, shit's situational. DRK's nice for e-peen numbers and most sky god fights don't last that long (..I hope), but:
Ixion is an asshole. Stick with /WAR sub, expect half of your SAs to miss because your RNG pulls hate and moves it, or the damn thing's just being finicky anyway.Originally Posted by Insoluble
It's hard for me to comment on some mobs as much (Khim or Cerb for example) because I usually just switch to DRK for the stuns or SAM for the damage.
Food
I like to stick with attack food when possible, but sometimes it's not always plausible on my THF for some of the things I fight. Maybe Thieves will full dagger merits can speak to it better than me. I'm surprised your accuracy is so awful with Pizza, though. . all I can say here is don't completely rule sushi out, depending on the situation.
I guess that was rather rambling. If you want to know things specifically by HNM, send me a PM or something (if you actually trusted any of the advice I gave), I didn't feel like accounting for every single mob the shell I'm in fights.
But a lot of people have said excellent things here. You're not going to go topping a SAM (unless it's a really gimp one) or a WAR, but THF damage is nothing to sneeze at. But we bring more to the table than just that (and placebo hunter) with collab/accomplice.
