Ive had a Bow level 74, and i changed to Blader from lvl 75+. As soon as i changed i noticed the huge increase in defence, however a huge decrease in Phy Attack. Im currently level 77, with a 70 - 75 (Cant afford level 76 + 77 pieces yet

) garment set and i can tank a fully farmed SOSun +7 Glavier, and thats without Castle Shield.
