Pondering early 4th job strategy

I would say at least get your blizzard to the point you can 1hit both red and blue harps(around 830 m.atk to do it without an ice Ewand with lv15 blizzard for a lukless mage. Only lv6 blizzard is required if you have an Ewand). And then life will be much much easier. Exp is definitely better than CL or other craps, and pot cost can be covered by selling leech easily.
