for DPH, use ful r8 with dex/reduce dmg taken/increase def + GOF dagger preferably with atk lvl/def lvl/dex.
for aps, stick to dragon gears. i wouldnt dream having 3.33 base aps in full r8 if ur not gonna donate to buy mats... unless ul farm patiently till u earn enough ec and mats.. (I heard some sin spent 50k+ ec and still not get x3 int wrist or x2 int plate.
and contrary to what the other guy said.. stick to hit n run tactics since u are new to sin and just came back to game recently.. (i dnt think ur sin can take much dmg or lock the opponent for now. u cn fight face to face once u have enough def and mastered the art of lock)
