I narrowed it down to Samurai, Dragoon, Ninja, Disciple, Ranger, and Paladin
Samurai -
Great one v one class, good mobility with wind walk, good damage with sword, nice DoTs, and good armor/hp.
Fun class overall if you wanna be a semi tank with good DMG output!
Dragoon -
Amazingly fun class! Great mobility, semi tank, good dmg output, and can chase/ run away from other classes.
Also, super jump is so much fun!
Ninja -
Great class if you wanna be sneaky. Want to quickly kill your for before he even know what just happened!? This would be a great class for you. Fun backflip, good sword DMG, and very good burst with eviscerate and blitz. Has low armor and hp, though
Ranger -
I haven't fought any rangers since the new class revamp, but they're a great class if youre good with a bow.
Paladin -
Very tanky!! Has semi good DMG output, self healing classes, able to use shields, and able to revive dead people. Also has a skill that has a % chance to light someone on Fire, and a skill that reduces DMG(I think xD)
Couldn't explain the classes much further, typing this on my phone. Sorry if any of my sentences sound weird/ have grammar mistakes(stupid grammar nazis!)
