i dunno how much good this will do, but i was playing on KMS and JMS testing out pirate on my old acc and my cousin's account (30 gunslinger). They're pretty good. Basically, they're exactly what people said they were going to be. Bowman + Thief. Just a couple problems though.
1. Dash (1st job), not as good as haste, only lasts for 20 SECONDS.
2. Somersault Kick (1st job) may attack 6 enemies at once, but range is pretty horrible.
3. Backshot (2nd Job, gunslinger) is great and powerful, but no accuracy.
4. Wings (2nd Job, gunslinger) allows you to glide, but not very helpful if you don't have haste or something.
5. Bomb throw (2nd Job, gunslinger) is powerful, but hard to aim with (you don't get trajectory path, aim with power)
Although those are the cons...it has many pros as well.
1. Powerful and fast attacking class.
2. You get Gun Booster by 2nd job.
3. Later skills have attack boosting effects with every attack.
4. Long Range!
5. You basically get your own Air Bomber later on (w00t Gravioter or something like that)
6. You get a Hurricane like attack at 4th job.
7. I think you can start shooting uber powerful cannons by 4th job. Not too sure.
8. And finally your Aerial Bomber can attack up to 6 monsters.
I'm not too sure about some of the skills, but it seems that this class pwns by the time you get to 3rd job. But yeah, I've only played up to the 2nd job so don't credit me for the 3rd and 4th job skills yet lol.
