Make the leveling of a DoH/L easier. Since there is nothing in the main quest that encourages you to level a crafting class. No reason a normal player should feel required to game triple turn-in leves to level a class in a cost efficient manner.

But mostly these are growing pains. SE has never released a AAA MMO before. Think if them like a little brother/sister, they have to touch the stove top before being taking the warning seriously.
