To save you a little digging as well, here's the skills
http://sleepywood.net/forum/showpost.php?p=7521422&postcount=881So far, infighters look like bandits meet crusaders, with some strategy involved in skill use. All sorts of punches, kicks, etc. 3rd job has power buffing moves that charge up and let you use strong attack skills, like a Sader
Gunslingers disappoint me quite frankly. Way too sin clone-ish. They fire faster, but have no critical, can jumpshoot, have double shot and triple shot as skills... bleh. They start looking a bit more like bowmen in 3rd job, with elemental mob moves, and weird summons. (Octopus, lolwut?)
This is still in Beta though, so lots of tweaks are still to be made.
We know most of the equipment up to lvl35 too, if you'd like me to find that for you.
