Damage is linearly dependent on Attack. The formula is:
Average Damage [AD] = Skill Multiplier [SM] * ATK * (1 + C.RATE * C.DMG)
Damage reduction depends non-linearly on Defense. The formula is:
Damage Reduction [DR] = DEF / (600 + DEF)
Conclusion: having more than 4000-5000 Defense is not very beneficial. Critical Damage at 100% C.RATE is more beneficial than Attack (gloves are better for C.DMG than for ATK).
