I leveled my SCH to 56 , then my static had me switch jobs for raid and I had to take a Tank from 50-56 with not even a side quest needless to say fate grinding in Churning or North Than makes leveling easy especially with the new bonus for 60s I believe so you should have no problem work in some dungeon runs i.e Vault and Library and you' ll be there in no time

also....High and Low roulette give about 200k per exp so yeah but you wont get your law bonus
