You need to take stat caps into account. If you're not hitting ~345 STR and ~305 VIT, then you need to work on that first (why are you settling for 320 each? do you not know that's irrelevant?). Double meld VIT in body slot. The critical hit potency garbage isn't getting you anywhere (placebo effects actually don't count btw). Imperial Operative Bracelets = garbage too. Get a Rubellite Bracelet/+1. Triple meld STR on your hands as suggested (shoot for around +40) and wear STR rings (hence the VIT melds on body: Cobalt Hauby). In your waist slot, keep it simple and get a veteran's field belt.

Axe with VIT is unecessary. Build a good enough group to get a moogle or garuda weapon. Accuracy is your best bet in the weapon slot since you don't want to waste time and money putting it on hands. Electrum rings are good to have on hand for swaps but keep in mind you can eat food that provides +34 accuracy (just 2 short of 2 HQ electrum rings), while you cannot get more than like 9 strength from food (and even if it's higher than that, it's nowhere near +36 you get from using 2 rubellite rings+1).

You can't look at gear as slot-for-slot. It must be considered as a complete set. Plan ahead and play to a jobs' strengths, but don't sacrifice to get something you only think is better, like crit power on warrior, unless bonuses like that come attached to others that help (ie. garuda weapons).

Here's my DPS loadout if that helps [useful stats]...

WEAPON: Garuda's Scream
HEAD: Paragon's Crown (work on this, it's an amazing piece of gear)
BODY: Cobalt Haubergeon [VIT+25 total]
HANDS: Cobalt Mitt Gauntlets [STR+40 total]
LEGS: Felt Trousers [STR+18/VIT+20 total]
FEET: Cobalt Sollerets [HP+100, optional tbh]
WAIST: Veteran's Field Belt
EARS: Explorer's Earring
NECK: Electrum Gorget +1 / Explorer's Choker (swap by situation)
WRISTS: Rubellite Bracelets +1
L.RING: Rubellite Ring +1
R.RING: Explorer's Ring / Electrum Ring +1 (see below)

Foods: Smoked Raptor (attack+41) / Mugwort Carp (accuracy+24)

Relevant stat totals: STR 345 / VIT 312 / Attack 536 / Accuracy 380 (while solo)

As you can see, no easy feat to get some of these melds, but well worth it in the end (plus I have stuff to sell as I replace it with Darklight). I am stat capped for my weapon and that is the first priority. You'll want to have an explorer's choker and at least one electrum ring +1 on hand for high-accuracy situations such as Garuda. The advantage to the way I melded stuff is that I was able to utilize an explorer's ring for extra attack in my build. This also has the secondary advantage of allowing me to swap out that slot for another +18 accuracy without changing my stats around. Similar logic is used in neck slot.

I'm not sure what got lost in translation after stat cap information was posted, but it seems many people are unaware how to gear themselves properly. I didn't really find the information confusing and thought it was rather straightforward.
