A lot also depends on the style of play you prefer, I don't think it's a good idea to pick a character solely on what is currently popular in parties. Otherwise it's a long grind and not much fun. :)
well you've picked the high end classes ie third class change occupations which will take forever to get to, so you wouldn't be a noob by the time you get there..
Generally speaking if you do want a party to depend on your skills don't role a support class such as BD as you will be expected to know when and what dances to do.
I'd go Gladi or TH for human, or PR AW or SH for dark elf
Just go archer/nuker and shoot at stuff.Leave the ppl that have played alot to worry how you stay alive.And when they tell you "No MP" you dont go and aggro 54512241 mobs okie?
