I strongly disagree with the OP stating that crafting is the largest problem facing the game. It is one of the few systems in 14 that was very strong from word go IMO.
As for wanting to make it less grindy, I disagree again. In an MMO I feel you need a variety of playing styles and speeds. I can login for NM camps/guildleve parties that are engaging and require my full attention, and I can also then switch the radio on, browse some websites and watch TV whilst crafting. It gives a GREAT change of pace to playing. A game should be relaxing as well as engaging and that is the strength of MMOs. You shouldn't have to give your full attention every second of ingame time.
I definitely agree that there needs to be more aspects to crafting, I'd love quests and leves that make DoH team up with DoW/DoM. Either crafting an item with a time limit whilst your party protects you from mobs, or an event where you rush to make/repair stationery battlements before an onslaught of mobs... something along those lines.
