My main goal is to be able to catch +3 Red Corals to make the crap bow. I think r45 fisher will be able to do that. At L45 I will be able to wear the L47 gears(even if I do lose some stats). With so many other jobs that actually need L50 to be more effective, I just can't justify grinding for hours/days with fishing past rank 45 at this point.

But there are plenty of grade 6 waters with no agro mobs around. That's not really an issue.
