Consider this...

The point of gathering, in it's simplest form, is to collect materials (to sell, or to convert into whatever items by yourself or a friend). Above all, at this point, to make money.

The point of crafting is to use materials (gathered or purchased) to create equipment to use or sell, your choice entirely. Again, above all, usually to make money in the end.

The point of combat classes is to fight cool mobs and bosses and raid whatever dungeons come up in the future, as well as to progress through the story (when more of that comes) with other cool fights, etc. Given that both DoH and DoL are left out of all the "coolness" so to speak, they make up for it in their own ways. Combat classes shouldn't be allowed to have all the fun (fight cool stuff, AND make a ton of money), so why are you guys complaining about that?

Morever, I think many people will level at least one crafting or gathering class to the cap (or close to it) in their time playing this game, so it'd be easy to just balance out whatever craft you don't have leveled with the one that you do. i.e.: make money on Blacksmithing to pay for a craft you can't do on your rank 20 Goldsmith.

Put it this way, if combat classes could: make money, fight awesome stuff, progress through story in a party setting with friends, wear all the cool armor, get cool abilities, etc, etc - what would be the point of ever touching crafts or gathering? (inb4 "some people like to play Farmville")
