A reply from future:
Yeah, but that would affect the balance, like a lot. I'm a bit hazy with details but armor is basically ranged defense while defense lowers the chance of getting hit in melee combat. The trouble is there isn't a parity between them, like you can't increase each by one to keep the balance, they scale differently and TW never made their combat functions known.

Would the battles increase if u boost def and armor? tbh I don't really know j, I'm ust asking,I haven't played the game in a long time.
