I think the build is weird for 4th job... Pretty sure I'm gonna max Pirate's Revenge before Cannon or Torpedo.

What I plan for 4th job (Keep in mind that I have no idea what I'm doing):

120: 1 Battleship, 1 Cannon, 1 Torpedo
121: 3 Pirate's Revenge
122: 3 Pirate's Revenge
123: 3 Pirate's Revenge
124: 1 Pirate's Revenge (10, max), 2 Battleship
125: 3 Battleship
126: 3 Battleship
127: 2 Battleship (10, max), 1 Elemental Boost
128: 1 Airstrike, 1 Wrath of the Octopi, 1 Bullseye
129-149: Splitting points between Cannon and Torpedo until they are maxed.
150-153: 9 MW

After that, I'm unsure.

Reasoning:
Obviously Battleship, Cannon, and Torpedo are your main skills in 4th job so one in each at least. Pirate's Revenge helps a ton by giving extra damage, I know this because I already have a buccaneer. Maxing Battleship gives more attack, thus better damage more so than putting into either Cannon or Torpedo. Then, I put 1 point in a ton of things... because I like to try things out. I believe that since I maxed Octopi and have 21 in Gav that putting one point in each of their 4th job upgrades would only help and it is just one point each. Bullseye at level one gives +1% damage, which also helps greatly even with just one point. At this time, I am unsure as to how Rapid Fire is so I have allotted no points to it as most of the guides that I have read don't say to put into it early or even midway into their builds. So I am left to assume that it's not that good. I'm unsure as to if I will put a point into it to see how good it is or not.

I thought ship wouldn't break anymore, would it? No point of using rapid fire if you're always on ship and ship never breaks.. The damage is inferior to cannon..
