Ask a Soul Master/Dawn Warrior Thread

Question, if I'm going DEXless I should maybe get 1 Soul Blade then max Mastery ASAP right? (Or get it to lv19) Cause I see lots of people in the other Dawn Warrior thread maxing Soul Blade first, so I'm wondering if they're gonna have more base DEX so they can actually hit stuff or what. I mostly want to max Mastery first for the ACC boost it gives.

Another question while I'm at it, how far would these equips get me if I want to go DEXless:

 Spoiler

I also have a 7 ACC Bandana, and a 17 STR, 16 DEX, 15 LUK, 21 ACC Zakum Helmet to Karma over from my other character. The beginner top+bottom are just for before lv35.
