First of all, the parry. When i use parrys, i really never felt the difference. I wild keep the same strategy that my gladiators can do the most damage and miss the least, and i only change from offensive(slash,lunge,bash) to parry(parry-lunge,slash,bash). But i really couldnt feel the difference, is there something im doing wrongly?

And secondly, armors. When i use armors, im confused whether its all the same as long as the armor weights are kept within the green bar, or its lighter the better. Also, if its lighter the better, tell me in which ways it is better. Thank you
