4th job Corsair Bossing Build

That depends.
This topic is about a bossing build.
Rapid Fire>Air Strike in terms of bossing.

It started as a bossing topic, then it devolved into a general build topic once people realized anegos were over hunted, bigfoots near impossible to solo, and black crow(I dont even know if heal luring works still.)

General intuition would tell me:

Cannon, Rapid Fire, Bullseye...and no mob attacks would make normal training almost impossible. Then again most pirates leech to about 15X anyways.

Hybrid build:
Cannon, 11 airstrike, 21 RF, max airstrike, max homing might be a better hybrid training/bossing solution.
