2 is a bad idea, if you have high def you can parry yourself to death
battles are time-based now, Gungrave. Parry would just accellerate your next turn. Say you have 2sec before next attack, it could reduce that by say, 75%, and you'd attack in 0.5sec.
3 is pretty good but i can see that becoming overpowered
yeah no doubt, it would have to be a small % chance to proc.
I mean now you can literally not add to DEF at all and not feel any major impact..
totally not true, you should get critted to death. if you have 1 DEF the oppoenent will have a 100% chance to get 1.75x damage! (uh oh.. do mobs not crit??)
As another thought, I think some significant HP gains tied to DEF could really squash that element of weak DEF (say, +3 to +7HP per point... I'll crunch some numbers and compare results with the +%Armor idea and see what feels right)
