Gunslinger Build (Lv. 10-200)

Another thing to consider is that, if you don't lag much, Rapid Fire won't "waste" bullets. For example, if a monster has 10k HP, and you do ~4k each hit with Triple Fire, you'd be wasting two bullets on the final kill shot. Those bullets could be better spent damaging another monster instead of on dead air. Whereas Rapid Fire does ~2k each bullet, less of them are used shooting dead monsters. You would have a greater experimental DPS to theoretical DPS ratio. Overall bullet efficiency though is a problem with using Rapid Fire.

Eh, if you've played a BM, you'll notice that sometimes the attack is so fast that hits are soaked up by monsters that are already dead. Meaning you'll waste a few shots regardless of what you do.

My only question is why not get in Air Strike a little earlier? It is a great training skill, and when I used it on a ps, at like lvl 120 and 30 air strike, with only like 500 dex it did 20k dmg x 15 all over the skele mapppp,,, so why not?

Air Strike is not an ultimate. It has the range and damage of an ultimate, but it only hit 6 targets and it has a cooldown period of 5 seconds.

Corsairs are not a big mobbing class. Air Strike right after Cannon is already very early.
