If i were aiming for barrier, i would use smart coat instead since it give me more SPR in general. Not to mention it give use magic resistance, which give protection against all mag damage ( including frost blade), while armor of light can only protect you from mag attack
Barrier. If you plan to use WoL or sasayaki as your main tank.
1. Harder to find an armor with magic resist and decent spr
2. Lots of heavy armor have better def bonus, with phy atk type resist, from future events as well. So this one is less valuable than other armors
you cant pop a few potions and afk the game for a few days? its not that hard man. you can get a plus 5 in a week without even playing the game. besides even if that person had no life, why is it your business. Somethings off in your life when youre telling others how to live.
