@Versonex: you get bonus from dagger, you don't get anything from katara.

Dont forget to cube your Emblem, that thing can get Att% too, so its more damage efficient to cube that than it is to do armor pieces~

I think you should hold off on cubing your glove. Focus on your weapon, your sub weapon and your main pieces of equipment, such as Root Abyss equips. If you have the funds and you haven't already got one, invest in getting a Superior Gollux Ring and cubing that in place of your glove. Scrolling can be done little by little once you're able to obtain the store coins.

faf katara does not count towards the set bonus though o_O

freaky...this is what im cubing too. along with gollux earrings, badge, shoes.

Definitely the weapons first. Dagger first, katara next, and then depending on what you want out of the gloves either that or the shirt first.
If eventually you're going for dojo gloves, I wouldn't even bother with the gloves.

Dagger and then katara... But why faf katara? Sw is way better.

Weapons > armors.

the weapons if they're already scrolled

Hard to give you an answer if you dont tell us the specific stats, but usually weapon > secondary
