While a weathered gladius is a fine weapon, I have to imagine that people will eventually want things made out of steel. If a whitemage can be a class despite offering mostly support abilities, I don't really see how the DoL/H can't be classes even though they do the same thing. Armour offers more of a defense bonus than a "Protect" spell ever will, and skills like "Ferocity" are entirely useless without a good weapon to power them into.
Besides that, Class doesn't mean "guy who brains people to death." A 'class' is a role that someone fulfills within a society. ****, if we want to nit-pick, people usually have greater need for food and clothing than they do someone to go slay a dragon. If anything, the DoW have less claim to the 'class' title than someone who makes pants.
All that said, I wouldn't mind if the DoL/H had some more rudimentary fighting abilities. Obviously I don't want a miner to start excelling at combat over a gladiator, but I don't see why if I'm out in the field and get accosted by an ambitious rabbit I can't simply plunge my pick axe into it's face and continue along my journey. I don't get why I cant' cast magic I have learned as a conjurer just because I'm a weaver.
I wouldn't mind if there were some class specific quests with engaging story lines and events tailored to the abilities of DoL/H classes, but I don't think the main storyline should suffer because the crafting classes need to have something to do as well. It would be a bit silly to have to pause the final fight with Bahamut for the fisherman to feed him a fish because SE had to have something for the fisherman to do.
