Defense status does not work.
With 0 defense, a Lv 2 Meadow Bumblebuzz was hitting me from 21 to 57 damage.
With 458 (Total armor + Steel Protection buff), the same mob was dealing the same amount of damage.
With that said, Mages/Archers are the actual tanks in the game, because of Regen/Heal skills.
Please fix this issue, because its OP.
