In terms of fun, I'd go for Ice/Lightning (totally not biased), then Thunder Breaker, lastly Xenon. Ice/Lightning and Thunder have truly beautiful skills and are unique classes on top of that.

Pick yourself one.. Stop seeking for help with picking classes, it's by far the simplest thing on this braindead game
End of the day, you're an unfunded scrub doesn't matter what you choose tbh.

Dawn warrior is a pretty good mobbing, bossing class. Bossing parties would love to have a dw as well.

Thunder breaker for combo attack if you like that. Although I won't pick this for bossing.

Xenon is kinda boring while training, but pretty good once you get to 4th job and lvled most skills. Funding xenon shouldn't be very difficult especially that it uses both pirate/thief stuffs, definitely good for bossing.

I/L isn't going to be cheap but definitely good at mobbing and bossing.

Except of course playstyle but you know who cares about that.

Xenon with the new star force for super easy funding
Ice lightning for the Elemental Decrease (so u can do full damage on RA, Gollux, etc.)

TB for the cool people chaining the attacks like a boss. <3 Anyway Tb is probably the worst class there is in MS... Their chaining is not even that great.. And even for the most funded, i see them using 3rd job skills for the chaining. the 4 jobs are pretty much worthless... It is like playing the original MS when 4th job never existed but it is probably the most OP class if you put TB during those times...

xenon should do it
