Me and my friend are both thinking about play a sword man class, he is thinking about a fencer, for me i am thinking more of a doppel or dragoon, will or party be lack of dps if we have more than one sword man class? thank you
Dont worry. You will be perfectly perfect to level together, especially as two swordsman. Atleast in the DPS department as Doppelsöldner and the calsses most often taken in its building poath are DPS machines. And Fencer is a decent Evasion tank on top of that. Only way i would see a party of two having even less problems leveling would be if one of you would be going a Cleric route. But that would only influence later stages of the game, where most likely you will have met other players to supplement your group.
So dont worry, play like you guys want to play the game 
Edit: Yes, perfectly perfect! xD
Omg thx a lot i was thinking to give up my lovely sword man and go for archer if needed:*( thank you sir
