Well I've recently gotten on the DRG kick and gone on a crazy leveling spree while reading up a lot on the job.

Aim at your stats like this.

Accuracy > Attack > STR > DEX > anything else

Your decent WSs are multi-hit (Double Thrust and then Penta Thrust). Accuracy is the big thing on multi-hit WSs. You could have a ton of Attack, but it'll do nothing if the hit misses. STR only affects the first hit of a multi-hit WS directly (aside from the fact that 2 STR = 1 atk as well). At much higher levels, when using single-hit WSs and having capped atk/STR, you'll aim at a STR build, but that's pretty far off.

Beyond that, being a 2handed weapon wielder, you really don't want to miss. It hurts you damage wise and TP wise a lot more than a single or dual-wielder. Your hits will always land for a lot of damage as long as they land so make it a priority to make sure they land.

When you get Spirit Link (which heals your Wyvern and damages you) try to not use it between fights, but rather, near the end before the WHM sits down. Spirit Link tends to piss of WHMs a lot.

Your gear is gonna look like crap. There are a handful of pieces that are absolutely hideous, but are by far the best pieces in a slot for a long time. When you hit 25, try to get a Republic Subligar. Nothing comes close (not even AF) to it until 63. Another noteworthy piece you should get is a pair of Battle Gloves at 14. These will also last you potentially untli very late in the game.

DRG is slightly different from some other melee jobs. I'd normally aim at the best DPS (Damage per second) weapon in a slot. Usually even if a weapon has high damage, it may have really bad delay, making it do less DPS. However, with DRG having jumps, you'll often want to aim at the very high damage weapons. Generally this means the Lances (and as you go up they generally have good DPS also).

For food, I'd suggest using Rice Dumplings up until the atk% on them caps (around level 50). Beyond that you'll want to use the appropriate sushi or meat depending on your acc gear. Most people will probably want to use Sushi. You can only really get away with meat if you have a Peacock Charm, Lifebelt and 2xWoodsman/Snipers.

If there's anything I missed or any specific questions, let me know.

BTW... about looking bad.
