4th job Corsair Bossing Build

I apologize if the pattern of logic is a bit butchered in this post, it was written in a hurry and a series of edits.

Can't you tap-shoot Rapid Fire just like Hurricane? I don't see how Rapid Fire limits your movement. Sure you can't jumpshoot with it, but its greater DPS makes up for it. Battleship limits your movement but that doesn't stop people from using it, does it? Even if you're only using RF for 90 second intervals, I'd rather have the power of a 4th job character in that 90 seconds than be a glorified 3rd job character. Rapid Fire already outdamages Burst Fire at level 5 and it's nearly twice as strong at level 30. Bullet consumption shouldn't be a problem since it's only used for 90 seconds.

Air Strike isn't that great of a mob attack with its cooldown and getting Battleship Torpedo right after Cannon makes you overly ship reliant. If you're planning on taking the middle platform at Skeles, you shouldn't even need a mob attack to begin with. In the skele mini dungeon, you're most likely going to be hitting 2 skeles at a time since your Bishop/Arch mage is going to be ksing the rest.

If you're duoing then you might want to wait till a much higher level first. If a level 15x Corsair's ship breaks that often then there's no way a lower level one can handle bottom without slowing down the spawn/exp. Thus, Battleship Torpedo can be postponed until late level 16x. That gives you enough time to max Cannon, RF, Bullseye and MW.

For these reasons, my build still stands to be: Cannon -> Rapid Fire -> Bullseye -> MW19 -> Torpedo. If Anego were a reliable training spot in Bera then I would switch Rapid and Bullseye around, but it isn't. Torpedo does look good for Time Temple training though. If it's out before I get to level 131 then I'll definitely get Torpedo after Cannon.

Have you actually begun to play your Corsair? There's no such thing as being overly ship-reliant. You have no skills that make up for not having a ship. Even maxed Rapid Fire and Elemental Boost pale in comparison to Cannon and Torpedo. Half of playing a Corsair is knowing when to have your ship out and when to protect it.

You can tap shoot like Hurricane. It's actually better than Hurricane in terms of mobility because it actually shoots when you jump shot it. That doesn't make it an efficient means of killing things. Tap-shooting is something you do as a BM when you can blaze through a mob. Rapid Fire is weak. Corsairs can jump shot like a NL, which is far better than tapping anyway.

Cannon is exactly why low level Rapid Fire sucks. You already have one skill for damage, why get another skill for a half-assed damage boost that'll come into play about once every 15 minutes when training for 90 seconds? You shouldn't ever need Rapid Fire when your ship is active. At Pap and Pianus my ship already lasts a good 4 minutes or so, that number's only going to go up as I gain more levels.

Rapid Fire is less than 50% stronger than Burst Fire when maxed, not twice. Level 5 Rapid Fire is less than 1% stronger than Burst Fire. Totally not worth it.

Does anyone wanna explain to me while Air strike is "such a nice skill to use"

I have level 1, almost never use it, and I do fine. I see it more of a nuisance as it aggros monsters, has a 5 second CD, and i just take unneccessary damage. It's better when they aren't aggro'd so i can freeze, get on my ship, and kill them.

Yeah, because your level 1 Air Strike doesn't do hardly enough damage to kill anything. Maxed Air Strike is intended to let you kill a group of monsters from a distance without climbing up ropes and attacking them at all.
