Should I switch to a bishop using the job advancement coin? Should I switch to a bishop using the job advancement coin? I'm a level 163 I/L mage and I was wondering if it is worth it to job change to a bishop, since I have two extra coins, maybe I could job change and level up to a certain level in order to level faster and then switch back for bossing? Also do I still have to buy mastery books when I change?
