Questions about Dual Blade

So my Dual Blade will have the world's worst equips like my aran. I'll probably end up using 100%'d equips or clean ones.

1) Should I go DEXless? Are DEXless even plausible for DB's? I don't want to have like 120 base DEX, lol. If possible, I want to go DEXless til I can upgrade equips.

2) Are Adventurer's Ring very beneficial to DB's? I heard Thorns work funky, so does Crit/Cruel ring help a lot? If not, I'll just use Lillin's Ring.

3) Is it likely that you NEED NX for the skills? Like will there be an alternate method of obtaining the skills sold in CS? (Basically, can you obtain Evans' skills like Magic Guard outside of CS now?)

1) No, Why?: KMSTlol
2) Adventurer's ring is #1 Lillins ring is a Close 2nd
3) yes it helps cause free stuff and its overpowerd.
