As far as i can tell, the physical DD's Lancer, Marauder, Pugilist, Gladiator and Archer seem to have roughly the same damage output. But the Damage of each class is really based off what kind of monster you are fighting. If it is a heavy armor type, the Piercing type damage of a Lancer will out damage the Blunt type of a Pugilist, or that is at least what i have seen so far. Thankfully each class has a few types of weapons they can use for each kind of fight.
So in the end each class seems to be roughly the same, just each has a heavy focus on one kind of damage, but still have a few other weapon choices to help them do a bit more damage to monsters they will not normally do much too.
Lancer weapons so far are as this.
Harpoon's are a mix of mainly Piercing and a little bit of Blunt.
Lance's are a pure Piercing type weapons.
Spear's and Halberd's seem to be a bit mixed but consist of Piercing, Slashing and Blunt type damage.
Well thats my opinion anyway hopefully it helps and if i am wrong hopefully someone will post about it properly :S
