Dbl Attk Or Store TP?

I asked for comments of improvement not criticism. Thx for the try though German.

Twilight mail is not bad, it's just not the top choice. Clearly it will beat Heca in any situation. If you get one and are on a budget, by all means use it.

You could go for Zahak's mail (much cheaper than Grim and very good) for buffed situations and mail for unbuffed ( Berserk / Restraint / Aggressor ).

Af3+2 hands modify the bonus, which is stored separately from the hands themselves. In essence the hands double the effectiveness of restraint for each regular swing (bonus doesn't apply to additional double attack or triple attack swings), but are not reliant on the hands being on during the ws.
If you were to wear them on a first hit, remove for second, put em back on for 3rd, alternating etc., your restraint bonus would look like this: Double, regular, double, regular, etc. It would still calculate those 4 hits as being equivalent to 6 hits in restraint ws bonus damage even though you took them off and reequipped like that.
TBH, I'm not sure if there are better hands for tp phase (there may very well be) since the reality is you're probably only really getting 2-3 swings that count toward Restraint bonus when using a 5-hit. This certainly reduces their effectiveness, but when you're shooting for a 5hit, your damage is shifting toward your ws frequency, so upping that ws damage in tp phase seems like the right thing to do.

AF3+2 Bonus too. Doing 1.2k crits on Scars/Visions NMs is cool.
Still really low proc rate, but cool.

For outside abyssea I can't imagine Heafoc being better than ravager's+2 because your dDEX won't be capped, though I don't think you'll ever need THAT MUCH accuracy. (20 on body 12 on hands 7 on feet, +7 skill on body. Should be capped on everything everywhere, specially with capped merits.)

He did offer some improvement help..don't buy NQ cerb ever. See that's helpful.

If you think at how much Acc we would have at our disposal back at 75 cap, there is nothing that should be evading us with the much better Acc gear and GA skill we have now.

Still, for outside Abyssea I would likely recommend swapping Heafoc for Hands +2, Legs +2 for BH.
Outside of Abyssea, just for dDex purposes, even Twilight and Adaman bodies might prove more beneficial than Grim or Zahak's, but I won't go as far as to say they'd always beat them as there are many factors that need to be considered.

Capped Haste, true 5-hit build without the Regain if you use Carbonara as your food.

My Ring2 doesn't show for some reason but I'd use Keen Ring or Hoard Ring if you don't have access to Rose Strap.

Edit: Can use Walahra Turban and still be capped Haste if you don't have Zelus.
