Would Final Attack increase the DPS of a 2HBW paladin?

Hey level 136 2HBW Paladin Here.

Would Final Attack actually increase the DPS of my Meme weapon?

I need some input on this.

 

but what about 4th job skill blast? that's what i'm talking about here.

 

thank you for the answer, so speed infusion mule it is then.

 

Final Attack only works with 1st and 2nd job skills
